Calling A C Function From VB

Calling An Oracle Package.Procedure Works But Calling A Function In The Package Does Not ?
Hi,

I am trying to call a function in a package in Oracle, from VB. I am using the traditional ADODB with connection, command and parameter objects. The function has 6 input parameters and it returns a string value.

We have no problems reaching the similar Procedure under a package, but when it comes to accessing the function, it gives errors. I got "no descriptor found", after some changes "object stored Procedure does not exist" .

Any suggestions on how differently to access a function within a package as opposed to a procedure ?

Thanks,
Arch

Calling A DLL Function...is This A "calling Convention" Problem?
Hi All, I'm not sure if this has been covered in another thread. I'm trying to call a function in a DLL that was written in C++ and its saying it can't find the entry point, I've got the case and spelling correct.

Heres the C++ example code of how to call it:
LONG DLLFUNC RotorRadioConfigure ( HWND, HANDLE );

and heres my VB code:

public Declare Function RotorRadioConfigure Lib "rr.dll" HWND, HANDLE) as Long



I've also tried using ordinal calls:

public Declare Function RotorRadioConfigure Lib "rr.dll" Alias "#1" (HWND, HANDLE) as Long




But, I don't know which ordinal number to use, I've tried #1 to #8, then VB crashes, there are about 15 functions in the DLL.

On each ordinal call, it just says invalid calling convention.

Any help?

Scott.

Calling A Vb Function From A Public Function
Hi,
I want to go through a bunch of worksheets and sum up a particular range. I am trying to call the Sum() function from my own public function but I get an error. Can I do this or do I need to write a separate function ? Is there a smarter way to do this ?
Thanks in advance,
Z


Public Function Cal_key_cust_vol(Customer As String, Qrt As String) As Integer

Dim tot As Single
Dim JobList As String
Dim Amt As Integer
Dim Q1_vol As Range

tot = 0: JobList = ""
For i = 1 To Sheets.Count

If Left(Sheets(i).Name, 3) = "Tst" Then
Q1_vol = Sheets(i).Name.Range("D33:L35")
Q1_vol_sum = Sum(Q1_vol)
Debug.Print Q1_vol_sum

If Q1_vol_sum <> 0 Then
tot = tot + Q1_vol_sum
JobList = JobList & Sheets(i).Name & " [" & CStr(Q1_vol_sum) & "]" & Chr(10)
End If
End If
Next i
Application.ThisCell.ClearComments
Application.ThisCell.AddComment.Text JobList
Application.ThisCell.Comment.Shape.Width = 300
Application.ThisCell.Comment.Shape.Height = 200

Cal_key_cust_vol = tot

Calling A Function From A Paramater Of A Function
Just a quick Q?. I've been told it's possible in C. But is it possible somehow
to call a function from a function parameter. e.g

Private Function CallFunction(byval strFuncName as String)
Call strFuncName
End function

Would be ideal for an app that I want to create to easily addin new procedures e.t.c

Thanx In Advance

Calling A Function, But Exiting Out Of The First Function Too???
I don't think this is possible but I am very curious about this.

I want to know if it is possible to exit a Function/Sub before/After I call another Function/Sub to run.

Example:

Code:
Public Sub Main()
Dim bTest as boolean
Dim lValue as Long

bTest = True
lValue = 12

Call fnNewFunction(lValue, bTest)

Exit Sub

Private Function fnNewFunction(lNewValue as long, bTestValue as boolean)

'Do Something

Call fnAnotherNewFunction()

End Function

Is Sub Main still in memory even after it called another function? I notice that it end exited the sub. So is there a way to make it exit the Function/Sub after a call to another Function/Sub?


Thanks

Calling Sub Or Function In A DLL
Hi, trying something similar, but in Outlook and dinamically. Let me explain:

I want a menu structure that mimics the sub-folders in a specific outlook public folder. The problem is that the folder structure is going to change over time. So what I want to know, is it is possible to create buttons dinamically on application startup (doesn't matter which Office app - I can change it to suit Outlook.

I can get the structure no problem - but to get the click event of the last level of buttons, I have to declare them and I don't know how many there are...

Any ideas?

Calling Sub Or Function In A DLL
Hello all.

I recently converted a bunch of my related macros into a Word Addin.

The addin adds a menu and submenus to one of the toolbars. The problem I am having now is my .OnAction events for each item of the menu are looking to the Normal.dot template for the specified sub... I have been unable to properly reference the sub in the addin dll where the actual routines are stored...!

Is it something like...

.OnAction = dllName + "!subName" ???

Any suggestions?

Thanks

Calling Function From A C++ Dll In Vb
I am trying to call a function from a c++ dll from a vb program. There are two parameters that ar passed into the function. The values are changed and passed back. When the function is called I get the message "Bad DLL calling convention" which means I have screwed up the parameter declarations. I have tried an asortment of variations without success.

A sample of the c++ dll code is:

TESTDLL_API int fnTestdll(int *n1, int *n2)
{
*n1 = 22;
*n2 = 33;
return 42;
}

I do have the def file:

; testdll.dll

LIBRARY"testdll"

;CODE PRELOAD MOVEABLE DISCHARGABLE
;DATA PRELOAD MOVEABLE

EXPORTS fnTestdll@1

The sample vb program is:

Private Declare Function fnTestdll _ Lib "c: emp estdlldebug estdll.dll" _
(ByRef v1 As Long, ByRef v2 As Long) As Long
Dim nn As Long
Dim mm As Long
Dim iret As Long

Private Sub Form_Load()
nn = 66
yy = 222
iret = fnTestdll(nn, yy)
End Sub

Calling DLL Function
I've got a dll written in c++ that I want to call from VB. The particular function I want to call accepts (const char *file) as a parameter. I also had trouble registering the DLL using regsvr32 so I thought I'd just declare the function in my code. So I've got a couple questions:
1) If the function expects const char *file as a parameter, what do I pass it from VB?

2) Why do I get "the.dll was loaded, but the DLLRegisterServer entry point was not found" when I try to register it?

Thanks for any help...

Calling A Function
i have been programming in php for awhile. so i decided the other day to learn visual basic. seems like a good language to learn. picked up the book "visual basic in easy steps".

i have gotten stuck on calling a function. the form is laid out like this.

centimeters: <list box is here>

In inches: <label2 is here>

<convert to inches button here>

i want to convert centimeters to inches. i keep getting an error when trying to call the function. so i took it out; just to see if what i type in shows up in label2 and it does. here is the code.


Code:
Function cmToInch(cmVar As Single) As Single
cmToInch = cmVar / 2.54
End Function


Private Sub Command1_Click()

Label2.Caption = Str(Val(Text1.Text))

End Sub

Private Sub Form_Load()

End Sub
can someone explain and show how this code should be written to call the function and convert centimeters to inches.

thanks,

Calling A Function From A Sub ?
Now this is probably a bit basic, but I have my VB6 book at work, and I would like to get over this hurdle...

How do I call this function from within say.. the form_load sub ? I wish to put a code in for the day as shown below, but I dont know g=how to call it like you do when you call another sub.


Function DateSerial(Year As Integer, Month As Integer, Day As Integer)
datecode = (Year + Month + Day)
Text1.Text = datecode
'deal with datecode
End Function

Calling A C Function From VB
I am trying to make a call to a C DLL function and I keep getting an error 49 “Bad DLL calling convention”. The DLL help includes a .h file for the DLL and the function is declared as follows:


Code:
int32 DllExport __CFUNC DAQmxBaseCreateTask (const char taskName[], TaskHandle *taskHandle);
My VB code declares the function as follows:


Code:
Public Declare Function DAQmxBaseCreateTask Lib "nidaqmxbase.dll" (ByVal taskName As String, ByRef taskHandle As Long) As Long
And I make a call to the function in my VB code as follows – taskHandle is a long - :


Code:
DAQmxError = DAQmxBaseCreateTask("Test", taskHandle)
I’ve tried just about everything I can think of to make this work but I can’t seem to get it right.

Any help would be appreciated.

Calling C Function
Hello folks!

I know this might be a stupid thread, but I really don't know how to call this C function from VB:


Code:
CRCDLL unsigned short int CRCDLL_CRC_16 (unsigned short int crc, unsigned short int len, unsigned char buf[])
{
unsigned short int i = 0;

for (i = 0; i < len; i++)
crc=(crc >> 8) ^ crc_16_tab[(crc ^ *buf++) & 0xff];
return (crc);
}
I am using the following call:


Code:
Private Declare Function CRC16 Lib "F:Documents and SettingsSebastian MaresDesktop23077CRC_DLLReleaseCRCDLL.dll" Alias "?CRCDLL_CRC_16@@YAGGGQAE@Z" (Result As Integer, Length As Integer, Data() As Byte) As Integer

...

Dim Result As Integer, ByteArray() As Byte
ByteArray = StrConv("Hello!", vbFromUnicode)
CRC16 Result, 6, ByteArray
When I use that, I get a bad DLL calling convention.

Function Calling
Hi, I'm new to this forum and to VB. All I am trying to do is to call a mnuSave sub function. I've already written the code and I just want to use it in the Exit menu item...so that each time you click 'exit' it will prompt you to save (and not just text so I cant use the RTF.SaveFile call).
something like:

Private Sub mnuExitItem
mnuSaveItem
Unload Form1

End Sub

Calling On A Function
i am not realy familure with moduals and stuff , if i have a function that i use alot like

if num = 1 then
bla bla
end if

i know i would declare num in a modual as a public integer, but say i want to call the function in my form with a button so when i press the button the button code would be

button_click()
num = 1
end sub

so when the button is pressed it will do the fuction stated above without having to type it every time i want the function to be used.
i hope this makes sence

Calling Same Function Before It Done...
Just wondering if this is possible, ex:

mainfunction, function1, function2, function3, function4

mainfunction calls function1, which calls 2, which calls 3, which calls 4.

This chain of event can take a long time... is it possible to have mainfunction start function1 (lets say) three times with 3 different sets of data. Once the first one of those 3 ends, it re-start function1 with a new set of data.... it would basically loop thru all of this data until done.

Dont know if this falls in multi threaded or not. I suppose this could be done with a array of a class, but then again, you run into the same problem as telling the code to "continue"....

Calling A Function
My code is below. I get an error: Compile error: Expect variable or procedure, not module. When I hit ok when debugging it highlights in yellow with frmControl: Private Sub cmdSaveconfig_Click()

I'm re-learning this stuff so maybe I forgot something. If I take the code from the module and replace the "Call Keycodes(frmControl)" with the code it will execute fine.

I have a module that has a function in it


VB Code:
Public Function Keycodes(frmControl As Form) Select Case config        Case Is = "a"        keycode = vbKeyA        Case Is = "b"        keycode = vbKeyB            Case Is = "c"        keycode = vbKeyC        Case Is = "d"        keycode = vbKeyD         Case Is = "e"        keycode = vbKeyE        Case Is = "f"        keycode = vbKeyF     Case Is = "g"        keycode = vbKeyG        Case Is = "h"        keycode = vbKeyH     Case Is = "i"        keycode = vbKeyI            Case Is = "j"        keycode = vbKeyJ        Case Is = "k"        keycode = vbKeyK            Case Is = "l"        keycode = vbKeyL        Case Is = "m"        keycode = vbKeyM         Case Is = "n"        keycode = vbKeyN        Case Is = "o"        keycode = vbKeyO     Case Is = "p"        keycode = vbKeyP        Case Is = "q"        keycode = vbKeyQ     Case Is = "r"        keycode = vbKeyR     Case Is = "s"        keycode = vbKeyS            Case Is = "t"        keycode = vbKeyT        Case Is = "u"        keycode = vbKeyU            Case Is = "v"        keycode = vbKeyV        Case Is = "w"        keycode = vbKeyW         Case Is = "x"        keycode = vbKeyX        Case Is = "y"        keycode = vbKeyY     Case Is = "z"        keycode = vbKeyZ        End Select End Function

Calling A Function
i found this interesting,

i tried to call a function this way


VB Code:
load_rx_values(a_index, b_index)

and it throws a compile error

expected: =

but if i do

VB Code:
Call load_rx_values(a_index, b_index)


there is no problem

does calling a function without explictly doing a call limit the function to one passed variable

Can i call the same function twice at the same time??

for example...

What happens if the function was called at the same time by 2 different calls ....obviously with different index's.

Will it work....or do i need 2 seperate functions??

Function Calling Itself?
Hi, I'm looking at a function that someone else wrote and I don't understand how the following works... basically when the function gets called, it performs some operations and if a certain condition is true, it will call itself. Now the trick is, say myvar="apples" the first time the function is called and then as the function is running, it changes myvar="oranges" and then calls itself. After the oranges run is done, the function will know enough to continue the "apples" run from where it left off. How does it remember a variable that was changed? This is just a simplified version of what this actual function is doing, because it will call itself in this nested fashion perhaps 5 times in a row and "remember" to return back to each previous run. It's just magic to me right now!

Calling A Function?
Hi,

I'm changing some code a friend wrote for me. Unfortunately she's gone to Spain. She wrote the code with a picture box in mind, but I'm changing it to a textbox - makes more sense.

In a command button I have:

Command1_Click()
Text1 = "We are being asked to find the value of 'x'." & _
"Firstly, we have to tidy up the left side of the equation,"
qShow
End sub

This then calls the function, qShow

It works fine for the code as a Picturebox:

Sub qShow()
If b < 0 Then Pictext.Print Trim$(a); "(x" & Trim$(b) & ")" _ Else: Pictext.Print Trim$(a); "(x+"; Trim$(b); ")"
End Sub

But if I change Pictext.Print to Text1.Text, I get the following error:

Compile Error: Expected: End of Statement, and ";" is highlighted. Could someone please tell me how to sort this out?

Thanks a lot!

Calling A Db Function From Vb6
Hi All
I've trying looking through the FAQs section and didnt see anything about my topic so here goes. In most of the applications I've written, I've done all the db work on the client side. Specifically in vb6, i would make a ADODB call up to the db, using a SQL statement to retrieve data from the table, and return it into a recordset.

However for this project, we are going to try to write some functions on the database side to do the work and handle the logic and my vb6 program is going to call those functions (pass in some parameters) and get a response back. I'm not sure how to do it and I've searched here and google without any luck. Someone else will be handling creating the functions on the db side. I just need to know how to make a function call to a SQL db from vb6. If anyone can point me in the right direction, I'd really appreciate it.

Calling A Dll Function
i have a dll called "swscan.dll" located at c:

i have written
"Public Declare Function SWDinit Lib "c:scan.dll" () _
As Integer"

and then tried to call :
"Dim iResult As Integer
iResult = SWDinit"

but all i get from
Dim s As String
s = Err.Description"

is the message "File not found : c:scan.dll"

What could be the problem ?

I have also tried to locate my dll into c:windowssystem32 with no results at all.

Calling A Function In A VC Dll.
Hi,

I need to call a function in a VC DLL that is defined like this:
COMMON_EXPORT void MyFunc (CString FileName, CString InputStr, CString *OutputStr);

I have declared the function in my VB program like this:

Private Declare Sub MyFunc Lib "Common" Alias "#2" _
(ByVal ProjPath As String, ByVal ProjVar As String, ByRef StorString As Variant)

And the call is:
MyFunc ProjectName + vbNullChar, "top_assembly:" + vbNullChar, TopAsslyName


But, it does not work.

Any ideas?

Thanks in advance.

Calling VB Function From C++ DLL
Hi,
I have a function in Vb whose declaration is

"Public Sub VBFunc(sn_String as string)"

Now I want this function to be called by C++ DLL(Test.dll). So I declered a method in DLL to get the address of this VB function:

STDMETHODIMP CTest::RegisterCallback(long fnPtr)
{
typedef void (__stdcall *FUNCPTR)(BSTR pbstr);
CComBSTR bAccString(pucStr); //pucStr is a global string
vbFunc = (FUNCPTR)fnPtr;
vbFunc(bAccString); //Access violation happens here &lt;=====
}

From Vb side I call this function as follows:

"Public o_Connect As New Test.APIs"

Then i called
"o_Connect.RegisterCallback AddressOf VBFunc" to register the address of the VB function.

When I try to call the VB function from DLL, (refer the function CTest::RegisterCallback above), I receive the access violation in the last line (indicated above).

Why does it happen like that??


Thanks and regards,
Girish V
