search a registry class work from this side and create a key with the name of your choice under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and use the path to your .exe as value.

So I have an exe and it's linked to a DLL. Wow! 
Exe code declares CString local variable and passes it to a function in the DLL.
That function assigns a new longer value.
So CString grows the buffer to put the new value in. Right?
This is in DLL.
But when CString code tries to delete old buffer
I get message box with
"user breakpoint... at 0x077f75a58"
and
ASSERT(_CrtIsValidHeapPointer(pUserData)) fires up.
I read something about _CrtIsValidHeapPointer and it says that each DLL can have it's own heap.
So how do I get around this?
Urgent! Please!
Thanks a lot!

In general, you can not pass allocated objects between DLLs and EXEs unless they share the same allocation routines. This would be done by linking against the RTL version of the C libraries.

I'm going to patent thought. I have yet to see any prior art.

Ok. Could you give a little more detail?
I'm a little confused.
What exactly do you mean by "linking against the RTL version of the C libraries"?
This is MFC CString class that I'm thinking using the same alloc routines.
How do I do this linking against the RTL version of the C libraries?

Hi,
I have tried looking at the examples available here but they don't seem to work for me. I have a SDI project on the go and I have a drawing window on the top right corner that I would like refreshed periodically. I want to double buffer it and this is what I have so far in my CDoubleBufferView::OnPaint()
CRect tempRect;
GetClientRect(tempRect); //rect of the window
CPaintDC dc(this);
CBitmap bitmap;
CDC dcMem;
if(m_isDoubleBuffered)
{
if( dcMem.CreateCompatibleDC( &dc ) ) {
bitmap.CreateCompatibleBitmap(&dc, tempRect.Width(), tempRect.Height() );
CBitmap* pOldBitmap = dcMem.SelectObject(&bitmap);
dcMem.FillSolidRect(tempRect, dc.GetBkColor());
Draw(dcMem);
dc.BitBlt( tempRect.left,
tempRect.top,
tempRect.Width(),
tempRect.Height(),
&dcMem,
tempRect.left,
tempRect.top,
SRCCOPY );
dc.SetTextColor(RGB(255, 255, 255));
dc.SetBkMode(TRANSPARENT);
dc.SetTextAlign(TA_LEFT | TA_TOP);
dc.TextOut(m_dwTopLeft.x, m_dwTopLeft.y, "Double Buffer");
}
}
else
{
Draw(dc);
dc.SetTextColor(RGB(255, 255, 255));
dc.SetBkMode(TRANSPARENT);
dc.SetTextAlign(TA_LEFT | TA_TOP);
dc.TextOut(m_dwTopLeft.x, m_dwTopLeft.y, "No Double Buffer");
}
I do not see any difference in either mode. Did I miss something. Btw, I am still new with MFC, thus if a more detailed explanation can be provided, it would be greatly appreciated. Thanks in advance.

Not the answer your looking, but just as effective and only like 2 lines of code.

I've got to Dialogs (DialogA & DialogB). DialogA has an edit box which I want to write to. DialogB consists of a few BUTTONS, when the user clicks one of these buttons I need a message to appear in the edit box of DialogA. Would some detail how this might be done using the following APIs
GetDlgItemText
SetDlgItemText
Kind Regards

Very simple, get the pointer of dialogA in dialogB, then in the eventhandler of the button in dialogB do the following
pDlg1->SetDlgItemText(IDC_XXX,"Text");

Hi !
I'm thinking about buying Visual Studio .NET.
I've heard and read many things regarding .NET and the need for the people using my application to have the CRT if it's not already installed on their machine.
My question is : is this true only for C# applications ? If I'm developping an app in C++ with .NET, will I get a executable which won't need the CRT ? Will my app work for example on Win98 ?
Since which version of Windows is the CRT automatically installed ?
Thanks for your infos,
Jerome

Visual C++ in VS.NET is the only tool that will generate native Win32 code. Therefore you don't need to distribute the .NET runtime (unless you use the .NET managed C++ classes)

Hi !
I'm having a problem wih the autolist member option.
Me and my coworkers are working on the same projet. I have on my disk a visual studio workspace, which includes 4 projects. My coworkers have _exactly_ the same configuration.
My problem : I want to have the autolist member when I type a class name, which is a class from the other project in the same workspace.
It works for my coworkers (the list of member variables and methods) appears in the text editor, but not with me.
I checked the options of Visual Studio and autolist member option is set.
Could anyone tell me what's wrong with my configuration ?
Thanks !
Jerome

There is nothing wrong in the configurarion, it is due to currupt .opt .clw files in your workspace directory...
Try deleting the .opt file (after closing ur workspace) and then load ur workspace in the visual studio.

Hi!
Is there any easy way to make your application to be multilanguage? What can be used for it? I want to let the user choose if he or she wants english french or german....
Well... I am a beginner ...
|
|
|
|
|
yeah certainly, You need to create resource only dll, this resource dll will contain all the messeage in the local language.
during application load time, load the appropriate dll to display appropriate language messages.

Hi everybody!
I think evrything is in the title...
I write a dialog based application, and I need to use the F1 key.
But I don't want to see a message box asking me where the help file is!
How is it possible to tell my dialog box F1 is a key like others?
Thanks!

don't know what i did but when i press the ClassView tap, i don't see the member variable any more. also when i enter code like: class. it suppost to pop-up the box to pick the member variable but now it don't show nothing. I'm a noob here, so those help me a lot. what did i turn off?
|
|
|
|
|
You didnt turn it off, sometimes it goes away when the intilisense database is currupt.... close the workspace deleteing the .opt file in ur workspace directory and reload the workspace.
this may help you, there is another way of deleteing the .clw file and adding the classes to the classwizard, since you said you are a noob, dont try it, coz it may f*uck up the classwizard.

For standard messagebox, there are push button options like MB_OK, or
MB_OKCANCEL. Could I change the caption of these buttons like in place of CANCEL, say EXIT?
Any quick method for that?
