Visual Basic :: Global Events For Keyboard SCAN CODE & ASCII CODE Event Trapping?

Trapping Keyboard Events
I am attempting to trap a CTRL + F and turn that into a ALT + F. Below is my code however, the sendkeys function does not work for some reason. Any ideas as to why it does not work?

Code:
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

If GetAsyncKeyState(vbKeyControl) And GetAsyncKeyState(vbKeyF) Then
frmMdiGlobal.SetFocus
SendKeys "%(f)", True
End If

I am detecting the key combinations. The form does get the focus but the SendKeys portion does not work.

Trapping Keyboard Events
Hi

I am working on an desktop application and my requirements are to trap Keyboard inputs like ATL+0 etc. I have to ensure that :

1. The keyboard inputs are trapped even if the Desktop application is inactive (in a minimised state and residing in the trap only)
2. Combination sets of ALT + 0 etc have to be trapped and some fucntionality be executed.
3. Not use DirectX

I have been able to do so using directx but then directx8 is not supported by NT 4.0.

Thank you in advance.

Key Press Event And Ascii Code In Unicode Environment
As part of internationalizing an existing VB application such that it supports Japanese, Korean, Chinese (i.e. all Unicode characters) not only English language.

The problem we are expecting is, in the current English version, we are having some key press events like

If KeyAscii = 64 Then
blnResult = False
'Do some thing here …
End If

Actually the above code takes the ASCII code (say character ‘A’) from the end user and doing some operation. How do we consider the same in Unicode version (i.e. in the Japanese version, the end user will enter his own character not ‘A’ as in this case)? Is there any standard methods/solutions are there while internationalizing an Application for these key press events? Please let me know.

Trapping Code? If Statement
Okay so this is my code that I've got set up.

Code:
Private Sub cmdCreate_Click()
txtresults.Text = "<TITLE>" & txtTitle.Text & "</TITLE>" & vbCrLf & "<META NAME=""AUTHOR"" CONTENT=""" & txtAuthor & """>" & vbCrLf & "<META NAME=""DESCRIPTION"" CONTENT=""" & txtDescription & """>" & vbCrLf & "<META NAME=""KEYWORDS"" CONTENT=""" & txtKeywords & """>"
If txtTitle.Text = "" Then
txtresults.Text = ""
End If
If txtTitle.Text = "" Then
MsgBox "You need to fill in all of the fields"
End If
If txtAuthor.Text = "" Then
txtresults.Text = ""
End If
If txtAuthor.Text = "" Then
MsgBox "You need to fill in all of the fields"
End If
If txtDescription.Text = "" Then
txtresults.Text = ""
End If
If txtDescription.Text = "" Then
MsgBox "You need to fill in all of the fields"
End If
If txtKeywords.Text = "" Then
txtresults.Text = ""
End If
If txtKeywords.Text = "" Then
MsgBox "You need to fill in all of the fields"
End If
End Sub

It works: if you don't fill in all the boxes you get an error and the text box will stay blank. But if you don't fill in more than one it gives you my error message(msgbox) more than once. Which makes sense seeing as I've got it typed in so many times. I guess my problem is, I don't know how to put more than one statement into an IF statement.

Code Trapping Error
My add movie form has many fields and NOT all are compulsory to be entered except title and movieID. The rest are optional. When I run my code after filling all controls, the records get inseted into the DB. If i leave out some of the fields on the form, then i get an error indicating that some fields were not filled.

How can i allow some fields to be left blank and still get the entered data captured in the DB?

Slow File Load Time...scan Code Question
Hello

I am working on a small app to load *.tga images. I need to get byte level info from the various format fields contained within the image.

I'm reading the file into an array called imagearray() but it seems to take WAY TOO LONG to scan it in. Is my selection of code appropriate? Do you know of a better way?

ASCII Code
Ok I know what function to use and have it show a letter as a number in a label, but how do you get it to show multiple letters as numbers.

Example: user types in the text box "Example"

the label would display : E=number X=number A=Number etc.

also another program im trying to code I need help with as well.

You click the command button and a input box comes up (I know how to code a input box) and the user types a # of words they will use to create a acronym, after that new input boxs come up for the amount they typed.

then those two words will creat a Acronym

example : Two words are Jack Lone, the label will have the first letter of both words displaying JL.

any help will be great thanks.

Ascii Code Into Characters
Hey all.
i am an UBER n00b at this site and to Visual Basic. Currently i am taking a visual basc class at school but that leaves a LOT to be desired. ok here is my delima, don't laugh, its extremely n00bish:

I have a program to take a string and display it in its ascii code. This part was fairly easy but now i want to have the program convert a string of ascii code into characters forming a message. This is the code for the encoding part of my prog:

Private Sub optEncode_Click()
Dim strMessage As String
Dim I As Integer 'index for next loop statement
Dim strChar As String
Dim strAscii As String 'the ascii code to be displayed
Dim intLen As Integer 'number of characters

strMessage = InputBox("Enter message for encoding", "Please Type Message")
intLen = Len(strMessage)
For I = 1 To intLen
strChar = Mid(strMessage, I, 1)
strAscii = strAscii & " " & Asc(strChar)
Next I
lblDisplay.Caption = strAscii

End Sub

Pretty straight forward. i want to use a similar code to "decode" ascii the problem is i don't know how i would distinguish between character codes within the string as some are 2 digit and other 3, etc. Pleaze help this n00b!

Ascii Code For Numbers???
On my program i have the ascii code for just letters which is:

cheers

ASCII Code Help - VBS Program
I have a program that needs to convert the 'phrases' entered by user, and convert it into ASCII code, and add '2' to the ASCII number and change it back from the new ASCII number to a letter character. So this is basically a code encrypter.

Example:

I enter "ABC DEF G" in text box
change "ABC DEF G" into ASCII Code
"ABC DEG H" = "65 66 67 68 69 70 71" in ASCII code
Then, I add 2 to each of the numbers.
"67 68 69 70 71 72 73"
Then convert it back to letters characters again
"CDE FGH I"

So it goes from "ABC DEF G" to "CDE FGH I"

Heres the code:

Code:
Private_Sub click (Command1)
text1= text1.text
For intNum = 1 to Len(text1)
intCounter = intCounter + 1
intJum = mid$(text1,intCounter)
intDum = Asc(intJum)
intBum = intDum +2
intCrum= chr$(intBum)
Print intCrum;
Next intNum

' This loops and gets every single letter character and converts it to ASCII , then adds 2, then converts it back again.

I use Len(text1) for the number of characters of each sentence
This code works, but how do I make it so that if I type:

"HELLO THERE"

It would be:

"JGNNQ VJGTG"

instead of:

"JGNNQ"VJGTG"

Because when I press [space], space is a character too, so it adds 2 to [space] number, which prints double quotation marks.

How do I make it so it keeps the space in the sentence, and not make " appear for [space]?
The code works, but

Getting A Char From It's ASCII Code
Hi
I'm writing a function to create random strings and I do something like

string = string + Chr(random_ascii_value)

It works to some extent but not exactely as I expect it to.
It only generates upper chars and simbols like : ; > =
The random_ascii_vaule is in fact at least 97 (ASCII code for 'a') and at most 97 + 24 ('z' I think).
Does this has to do with 2 bytes strings (unicode?) or what?
So how can I generate the plain char for a ASCII value if CHR doesn't do that?
Thanks
