You shouldn't need to use the escape character for back-slashes within a string, should you?

I'm fairly certain it works without them.

~~CString Destination= _T("C:\\Test\\");<br /> Destination+= PathFindFileName(source[aq]);<br /> Destination+="\\0";~~

CString Destination= _T("C:\Test\");<br />
	Destination+= PathFindFileName(source[aq]);<br />
	Destination+="\0";

try that.

Can you put a watch on your Destination string and tell us what that's filled with afterwards?

Problem using CLR in MFC ActiveX controls

I recently discovered MFC support for winforms, and have been using it to host .Net Controls in my MFC activeX controls. This all worked beautifully, until recently when we started getting an assertion from msilexit.cpp during shutdown of the hosting application. The assertion is due to a user breakpoint, which originates from the __clrcall _exit_callback function.

extern "C" void __clrcall _exit_callback(void)
{
...

if ( *__onexitend != NULL )
(**__onexitend)();

...
}

Here are the facts that I have been able to collect.

1. There are no exceptions generated after you dismiss the assertion.
2. The application seems to have no problems in release.
3. There seems to be a correlation between the assertion and the number of "clr enabled" activeX libraries that have been loaded into memory. The magic number seems to be three. If you only load two "clr enabled" activeX's during the application lifetime, no assertion.

My output window, when the assertion occurs, looks like this:

'VRExplorer.exe': Unloaded 'F:\VirtualRack\Trunk\Source\BuiltComponents\Debug\VRSystem\VRGUIControls.ocx'
'VRExplorer.exe': Unloaded 'F:\VirtualRack\Trunk\Source\BuiltComponents\Debug\VRSystem\VRGUIPanelWatch.ocx'

'VRExplorer.exe': Unloaded 'F:\VirtualRack\Trunk\Source\BuiltComponents\Debug\VRSystem\VRBitmaps.ocx'
The thread 0x11d4 has exited with code 0 (0x0).
The thread 0x16ec has exited with code 0 (0x0).
The thread 0x230 has exited with code 0 (0x0).
The thread 0x11bc has exited with code 0 (0x0).

Have look at the following article. It is more than you need, but it has one single left panel, and the right is split into two panels. Splitting one of thos would give you three...

Hi,
I have used TryEnterCriticalSection for thread synchronisation, It throws error during compilation,though i have defined the macro _WIN32_WINNT as 0x400 .

Please tell whether i need to do something more.

Which version of visual studio are you using? If you are using VS6, you have to install the SDK to get those declaretions.

ok.

Have you integrated the platform SDK with the VS6?I mean the include folders, lib folders etc.
If already integrated, ensure the SDK include folder is placed first in that list.

I hope you have set the _WIN32_WINNT macro in the project settings itself.
Also open the winbase.h file and ensure the function exists in that file.

macro should set to _WIN32_WINNT=0x0502 if it windows xp or make it >0x400 in the project settings itself.

Just a suggesstion, please don't flame me for this post. why don't you dynamically load the dll and call funcition from it. atleast your program would be compiled!

Hi, I've had this problem before, and instead of trying to figure out which WIN32_WINNT blablabla is not set, I suggest you copy/paste the function declaration to the cpp file.

Add this in your cpp or header file:

extern "C"
{
	WINBASEAPI
		BOOL
		WINAPI
		TryEnterCriticalSection(
		LPCRITICAL_SECTION lpCriticalSection
		);
}

Some version macro probably wasn't defined. This is a problem sometimes with VC6, I've found out that some things are missing because VC6 is too old.

Re-Posting as Question... Dialog - PropertyPage Problem

Rangarajan Varadan29-Sep-08 4:52

Rangarajan Varadan

29-Sep-08 4:52

I have an application which has a Dialog and a Tab control, each tab is a PropertyPage.
I don't have a OnInit handler for my Propertypages.

The situation I ran into is because I had to create a menu in the main dialog.
I have a Edit control and CComboBox in my Property page PPOne.

In my file menu, I do File Open, through which I can open a file and read its contents, am able to populate memory,then I perform the step m_oPPOne.Create(IDD_PP_ONE)(this is from a class derived from Ctabctrl) I see the tab appear, now how can I make the the data for the controls on this PP appear in their fields ?.

Example: Normally when I am on the PP if I click a button, this below function works fine.

void CPPOne::OnBtnRefreshClicked
{   
UpdateData(TRUE);   
//populate Edit controls   
CString str;   
str.Format("%d",some_int1);   
cs_my_edit_control = str;   
UpdateData(FALSE);   
ccb_my_combo_box.SelectString(0,*(&my_predef_Str[0+some_int2]));
}

But if I call this above function from my main dialog, it fails on the UpdateData line(s) with a assertion failure in line 4184 of wincore.cpp saying doing UpdateData before DoModal.

How can I overcome this? any suggestion would help.

Best Regards
