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

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\VRServiceLoggerPanel.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).
VRExplorer.exe has triggered a breakpoint
Thanks for your help,

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.
|
|
|
|
|
Ya iam using VS6 and I have installed SDK too.
|
|
|
|
|
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.

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);
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
RV

The details of your current problems can only really be fixed by you and a debugger.
Have a look at the code around the ASSERT - is it complaining that your calling UpdateData on a window that hasn't even been created yet? But if that's true, how can you get a button to be clicked unless it's on a valid window / dialog. Unless you are calling this method manually...
Which you say you are. At what point do you call the above function? Is it's before you have all the windows created, you'll be in trouble.
Etc.
You need to litter your code with breakpoints, and keep a very close eye on the m_hWnd member of your dialog and controls.
Iain.

you're right about that, the problem seems to be unique to this situation.
I am calling this function AFTER the tabs are created.
for whatever reason, the value passed to the function in wincore.cpp(just above line 4184) is a 1 when the error occurs, which suggests the data is being transfered from Screen/Dialogue to memory, while I am expecting it to go from memory to Screen.
But Thanks for the inputs....
Best regards
RV

UpdateData (BOOL bSaveAndValidate = TRUE)
It's not a spooky coincidence - you are calling it with true, which says "take values from screen, and put them into my variables".
But the other window creation stuff remains.

The GetPrivateProfileString function strips leading whitespace. Is there an overload that doesn't, or will I have to write my own?
eg
[Example]
SomeValue=" foo bar baz"
(not code, but needed to preserve spacing)
I want to get the 6 leading spaces in front of foo in the buffer.
