Is There A Command To Clear Memory ?
I have an application that uses 3rd party objects to retrieve images from a FileNet server. There is a memory leak in the 3rd party code that does not release memory when the retrieval process is complete and eventually hangs the machine.
The application runs around the clock and runs the retrieval process at whatever time is scheduled by the user.
Even shutting down the application does not free up the memory, the PC must be rebooted.
Does anyone know of a command or API that might help clear out the memory ?
Thanks for any info.
Clear Object From Memory While Using It?
I have a VB6 program solution thats really bugging me. I have a main form that has a CreateSubFrm button which create an instance of a sub form if there is not one created already. On the Sub form is a Exit button which unload itself. After clicking the Exit button on the sub form (it unload and disappear) the CreateSubFrm button on the main form do not work any more. The reason is the object (objx) of the sub form is still in memory and exist, so when u click the CreateSubFrm button again the IF statment is NOT true that objx = Nothing and will not let you create the objx.
The way I got around this is to raise an event in the sub form and set objx = nothing in the main form.
Now this seem to me a really untidy solution. Does anyone out there know the proper way of solving this solution??????
Below is the code.
Private objx as frmSubForm
Private Sub cmdCreateSubFrm_Click()
if objx is nothing then
set objx = new frmSubForm
Private Sub cmdExit_Click()
How To Clear Autoredraw Image From Memory ?
I have a MDI form which might load maybe a 20 or 30 MDI documents at the same time. The MDI form that's loaded multiple times, have picture boxes which autoredraw properties is set true. This is the fastest way i can implement a flickerless output. (You may advice back buffering in memory and BitBlt it to screen, i tried and it's not fast as Autoredraw).
Anyway, it's OK when only 5 or10 MDI documents loaded but after 10 or 15 it says that "Autoredraw image can't be created". I think it's getting out of GDI memory.
As you see, i just use Autoredraw just for back buffering (for flickcerless output). After my drawing is done i want to get rid of the buffer image (clear form memory) that VB creates when autoredraw is set to true. This is where i want your help.
Thanks for your interest...

Clear Nested Array Structure Memory
I've I several structures which are arrays and which are nested under a single structure (call it Top) which is also an array.
It appears (???) that by erasing Top, that the rest of the array structures still exist and remain in memory (Getting Out of Memory Error).
Does anyone know whether:
1) Just erasing the Top array structure will clear all underlying (nested) array structures?
2) Each array structure must be erased independently?
3) How to verify whether the structures still exist in memory?

Script That Will Clear Cookies/click A Button/clear Cookies...
Hi everyone, my Visual Basic knowledge is minimal. I used VB when its latest version was v6 long long ago... (2002-2003) And I was only able to create basic applications.
Now I need a script (or whatever that will do the job) to do this:
- Clear cookies in my browser
- Click a checkbox
- Click a button
I want something that can do this over and over again. I'd be really really glad if you could explain it in detail or give me some document links about it. Thanks in advance.
Shared Memory File - Memory Leak (URGENT)
I use a Shared Memory File, for caching data. With an ActiveX dll my applications read certain data out of the memory file.
When creating the ActiveX Object, the dll accesses the memory file in the Class_Initialize function, unmaps and closes the handle in the Class_Terminate function. After work, the Object is destroyed (Set Object = Nothing).
Whenever calling the CopyMemory API...
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (dest As Any, Source As Any, ByVal bytes As Long)
...from the ActiveX dll to read data from the shared memory, the used memory of the application that created the object, rises for exactly the lentgh of bytes read by the CopyMemory function, and is never released. Not even if the object is destroyed.
thanks for a fast answer.
Memory Unable To Be Read - Can VBA Perform A Memory Drop
While running some of my more memory-intensive VBA macros, the program sometimes crashes because "memory unable to be read." Is there a VBA command to dump memory in between sections of my macro so it does not use up too much memory at once? I've used "Application.Wait Now + TimeValue("00:00:05")" as a way to pause the macro in between sections but I'm hoping there is a way to clear the computer's memory.
BitBlt: Desktop To Memory, Memory To Picbox
I'm very new to this BitBlt thing, and to graphics in general - Excel gal venturing outside VBA - so please keep your explanations on a newbie level.
I wanted to learn BitBlt, so I thought I'd write a screenshot maker and try some different approaches to see how it all works. Three out of the four things I tried work as they should. The fourth one doesn't work at all, and I cannot see why. (All four are in the attachment.)BitBlt from desktop DC to picturebox DC. That works, except it doesn't update when I resize the form and the picbox, but I understand why it doesn't, so that's fine.BitBlt from desktop DC to a memory DC and from there to picbox DC. Re-BitBlt from memory DC to picbox DC whenever the picbox is resized. This is the one that fails completely.Resize the picbox to screen size, then BitBlt from desktop DC to picbox DC. Works fine.BitBlt from desktop DC to memory BMP, copy from BMP to clipboard and from clipboard to picbox. Works fine.Since I have 2 fully workable approaches (thanks to Deadalus who helped me get this far!) I'm kind of OK, but it bothers me that I can't see why the last remaining one doesn't work. I'm probably overlooking something simple, but would appreciate help figuring out what it is.
Memory Store && Memory Recall In Calculator.
Hey guys, for a project i am required to create a relatively basic Calculator. I have got the calculator with basic features, including Squared and Square root.

Strange Memory Leak With Memory DC
I'm using a memory DC to paint an image before i update the image to the screen. I use a timer to keep the image updating like this...
Private Sub tmr_Timer()
.Rectangle 0, 0, cDC.Width, cDC.Height, 0, vbWhite, vbWhite
If UBound(cTXT) > 0 Then
Dim A As Integer
For A = 1 To UBound(cTXT)
.Blt cTXT(A).x, cTXT(A).y, cTXT(A).Width, cTXT(A).Height, cTXT(A).hdc, 0, 0, BLT_AND
cIP.Draw(P.hdc).Blt 0, 0, cDC.Width, cDC.Height, cDC.hdc, 0, 0, BLT_STD
It runs fine for a while but then the graphics that im storing in my memorydc are bleeding on to either the VB IDE when im working in there or on to the desktop when i'm running my binaries.

How Do You Clear A Db?
Every time I need to use my db, new info needs to be written to it. So all the old info has to be erased. How do you erase a whole access db though?
On A Clear Day....
Does anyone know if you can make a form (not a control) transparent so only what is on it (like a picture) shows up over any other forms which may be on the screen?
Clear A From
i have various forms in my database that as I select a project, will fill all the field on the form.
Rather than writing
everytime I have to clear the form, I thought I would write a function, where I passed in the form name, and then clear the fields, sort of like this
Public Sub ClearForm(strFormName As String)
Select Case "strFormName"
and then from the calling form
for some reason the me.name, although is the name of the form, doesn't pass it to the clearform sub because it doesn't recognise it in the select case statement
can anyone give me a clue as to why it is doing this
Im just wondering about a .clear method in VBA.As in Code:fsheet.clear.Does this method exist?From what version of excel on is it in.Is there anything equivalent I can do if my version of Excel doesnt have the method in it.thanks.

Clear Txt File?

Clear Button For Tic Tac Toe
I am having a dilemna regarding my coding for my clear button in a tic tac toe game that I have created. I want it to clear the screen so that another game can be played. Unfortunately, the way it is now is when you click the clear button right now you get the message box that we created coming up and saying you win. It clears the screen but only after you click ok for the msgbox 3 times.
Could someone take a look at the .frm and .vbp files I have provided a link to and let me know how to fix this? Thanks

How Do You Clear Out An OLE Container?

Err.clear Does Not Work
I have the following routine:
For i = LM To 12 Step 1
On Error GoTo ErrorHandler
i= i +1
The error handling routine works fine the first time, but the second time, it gives me run-time error 91. I belive that the problem is that err.clear is not working, since err is not reset it stops the macro from running when a new error occurs. I have tried to used err.clear in the past and it never works for me. I am using VB 6.0. Any sugestions.
Clear All Textboxes
On a user forn i want to clear all textboxes. Therefore i tried something with "OLEObjects ("Textbox" & i)". That's not the trick.
I want to find a way to loop through all textboxes on the userform.
clear checkedlistview without clearing all items from the listview, basically whenever I hit save have it reset all the checked items back to unchecked.
i Have a collection with many items. how would i use a codo to remove all the items.
Clear All Textboxes
I have 4 textboxes like this:
its basically a calculater this is the code:
Private Sub Total2_Click()
rubie = Val(Rubie1.Text)
diamond = Val(Diamond1.Text)
emerald = Val(Emerald1.Text)
crystal = Val(Crystal1.Text)
trubie = rubie * 10500
tdiamond = diamond * 5600
temerald = emerald * 4200
tcrystal = crystal * 560
Total3 = trubie + tdiamond + temerald + tcrystal
Total1.Text = Str$(Total3)
its a pretty simple code but now i want to add a button that erases all of the values to like start over so all of the text boxes are empty. instead of the user having to go and erase everything.
Anyone know what to do?
I have built a userform for entering data into Excel.
I have a couple of questions.
When I click OK the form doesn't clear out the data so that I can
start a new entry, is there something I can do about that?
Also I have a command button to open the worksheet,
but I would rather have it auto open, but if the user has no data
they can click cancel and view the sheet.
Any help would be great. Thanks
