Move casting to left side of assignment:
EDIT - it should be FARPROC &
(FARPROC & )fnDllTestPtr = GetProcAddress(...);

Use Dependency Walker (depends). There is a (usually old) version in the Platform SDK. You can get the latest version from http://www.dependencywalker.com.

The function name in a DLL can be viewed using Dependency Walker that comes along with Microsoft Developer Studio 6.0. It shows as Depends in the tools panel of Developer studio

Background...
I'm using the msado15.dll ADO type library for database access.
I'm using a class derived from CADORecordBinding to bind to a _RecordsetPtr object, which I'm using to update a list view with. The class is given below.
I'm currently reading the MailID field out of the database as an adVariant type, but it's actually an adGUID type.
The reason I'm reading as an adVariant, is that I'm not sure how to store an adGUID type as a c/c++ variable.
I'm a bit new to all this, so please forgive my greenness!
Destroying the CMessageHeadersCache Object...
You'll notice that there are COleVariant member variables in the CMessageHeadersCache class. When I call delete on objects this class, the program crashes! When the COleVariant member variables are absent, deallocation goes just fine! I'm sure that there must be some safe/correct/appropriate way of deallocating these objects containing COleVariants, but I'm a bit stuck! Please help!
Many thanx,

How to get a pointer of the view object into mainframe?
|
|
|
|
|
This code is by Craig Henderson:
CView *GetActiveView(void)
{
CFrameWnd *pFrameWnd;
pFrameWnd = (CFrameWnd *)AfxGetMainWnd();
if (pFrameWnd != NULL && pFrameWnd->IsKindOf(RUNTIME_CLASS(CMDIFrameWnd)))
pFrameWnd = ((CMDIFrameWnd *)pFrameWnd)->GetActiveFrame();
return (pFrameWnd == NULL)? NULL : pFrameWnd->GetActiveView();
}
This function will always return the active view in an SDI or MDI application.

Hi,
Im trying to profile some code to determine where to concentrate in order to speed things up. Obviously i want time statistics. This is the first time ive tried to use profiling. I've successfully generated a pbt file, and im trying to convert this to a text file using PLIST. I can produce function coverage output fine, but whenever i attempt to produce time statistics, PLIST gives me the following error.
PLIST : warning PRF4481: clock frequency is zero
I can assure you, my clock frequency is not zero....Does the profiler have difficulties with GHz machines, or am i doing something stupid or....?
Any suggestions are welcome.
Thanks,
Alex

Have you merged the .PBO file yet? Perhaps doing a 'prep /M filename' will fix it. Otherwise I don't know...

Hi,
I think there is some kind of limit to the number of characters that can be displayed in a status bar. It seems to be 127 characters. I was wondering if there was any way of increasing this? It doesn't matter how wide I make the status bar, the text is always cut off at that limit!! Really frustrating.
Thanks in advance
(by the way, I know it's not my string variable that's cut off, 'cause I checked)

From the MSDN docs for SB_SETTEXT:
"The text for each part is limited to 127 characters."
You may try to host a static control as a statusbar child.

I have a dialog based app and I create a new dialog in the resource editor. In the main dialog. I put a button that will show the new created dialog, like this:
CTheDialogDlg dlg;
dlg.DoModal();
But now I want to press some more buttons on the main dialog or edit some edit controls... But it's not allowed... Hot make it possible!?
I've tried making it WS_CHILD and try making the parent window to be the desktop window instead of the main window. but it doesn't work... HELP!

Your problem is that you are showing the dialog as as a modal dialog box. Modal dialog boxes require the focus until they are explicitly closed, a MEssageBox is another type of modal dialog box.
What you want is a modeless dialog box. You can make it appear by calling the Create method of you dialog rather than the DoModal method. When you want the dialog to disappear you can call ShowWindow to hide it, or you can detstroy the dialog when you no longer need it.

You need to use CTheDialogDlg as modeless. When you call dlg.DoModal, main dialog becomes disabled until secondary dialog is closed.

DoModal creates a modal dialog, this gives the dialog control until it is closed. You'll need to create a modeless dialog using the Create method and ShowWindow. Have a search on MSDN for Modeless dialogs there will be lots of examples.

I'm writting a COM plug-in for a service. I'm able to register and unregister the dll with the service. Even after i unregister the dll I still get that error because the file is still in use. When I check with the service it reports that its not using my dll. I thought that the COM library knew when nothing was using a component and would release it.
I'm adding features and debugging my dll so I have to compile it often. I don't want to reboot my computer each time I want to comple the component. Is there a way to manually release this dll?

Is it a COM+ app ? It could be getting pooled and need stopping in COM+

Did you find a solution to this?
I'm facing a similar problem working on creating ShellExtensions.
Thanks!
|
|
|
|
|
Happened to me as well.
Attached the shell extension dll to SearchFilterHost.exe for debugging purpose, after the debugging finished I need to rebuild the dll but encountered the problem abovementioned.
Solution is to stop SearchFilterHost.exe in task manager afterwards.

Does anyone know of a method to return a list of files that a current executable is using? I will be doing this in C# but would like to get some input from anyone. Thanks in advance.

What do you mean by 'associated files'? File extensions associated with an application? Or files open by the app in given moment?

Any supporting files the executable requires to run.

If you have unmanaged .exe - like the ones produced by VC6 - you can use depends.exe to check which .dlls program is explicitly linked to. However, program may load any .dlls at runtime with LoadLibrary and link to their functions with GetProcAddress.
Managed assemblies created by C# are totally different story.

I guess I was looking at the Bigger picture, not just the application that I am going to be working on. I understand there are many million different ways to do things, especially when different languages are feasible for an operation, I guess it was more of a philosophical statement really.

You need to use the depends utility. Is under Visual Studio Tools menu....
