More information is needed (you've supplied almost none). For example, what framework (if any) did you use? Can you post some source code (in particular the IDispatch implementation)?

Hi Stephen,

Thanks for your reply.

I have create a new application with MFC Activex control wizard I have kept all default setting.
Then I have added the property Font with Implementation as Get/Set and then I kept two break point one in GetFont and another in SetFont.
When I try to debug that control using Activex control Test Container I can move to Getfont when I Invoke GetFont function but I am not able to move to Setfont function when I invoke Setfont instead it moves to GetFont function.

The first thing I'd test is if the debugger is telling you the truth: putting MessageBoxes with the names of the methods in the two functions is a quick and dirty way to verify this. I assume you're debugging with the debug build? Assuming this doesn't clear things up post your Dispatch Map[^] (post all uses of the macros in the link I gave).

It looks like you actually haven't a SetFont method in your interface. Could you please post the relevant code? You should also move your post to the COM [^] forum for better help.

Hi Pallini,

Thanks for your reply.

If we add a property with get/set for font we get this code. I have kept two beak point one in GetFont (return NULL) and another in SetFont(SetModifiedFlag();)

if I Debug using Activex control Test Container.When I invoke Getfont it goes to Getfont Function .But if Invoke Setfont it move to GetFont Could help me in this part to solve this issue.

LPFONTDISP CMySampleFontCtrl::GetFont()
{
// TODO: Add your property handler here

return NULL;
}

void CMySampleFontCtrl::SetFont(LPFONTDISP newValue)
{
// TODO: Add your property handler here

SetModifiedFlag();
}

You should show us also how these methods are mapped to the COM interface (i.e. the relevant MIDL generated code, if I remeber well...).

Hi ,
Thanks for supporting me.
I got the answer for the question which I have asked.

we can override OnFontChanged through which we see the changes when we invoke SetFont

Debugging Release version, built without debugging info, may lead to apparently strange results, I believe.

Maybe other codes bring memory error.
BTW, you can use CString here.

Hi, i don't know FlexGrid but here's a general tip: when you specify a font for your cells or maybe for the entire grid, use a greek charset. In the LOGFONT struct there is a member called lfCharSet, if you set this to GREEK_CHARSET, the font mapper will try to give you a font that has greek characters in it. As said, i don't know the Flex Grid so i don't know how you can make it use a certain font but i guess you will know that. I hope this helps somewhat.

for Visual C++ try this otherwise getenv will work
using namespace System;
using namespace System::Collections;
int main()
{
Console::WriteLine();
Console::WriteLine( "GetEnvironmentVariables: " );
IDictionary^ environmentVariables = Environment::GetEnvironmentVariables();
IEnumerator^ myEnum = environmentVariables->GetEnumerator();
while ( myEnum->MoveNext() )
{
DictionaryEntry^ de = safe_cast<dictionaryentry^>(myEnum->Current);
Console::WriteLine( " {0} = {1}", de->Key, de->Value );
}
}

That's not C++, it looks like Managed C++ (which isn't really C++ but a different language based on it). This is the wrong forum for code like that.

One minute of googling turned up this code:

#include <stdio.h>
#include <stdlib.h>
extern char**_environ;
 
int main(int argc, char *argv[], char *envp[])
{
  char **next = _environ;
  
  while (*next) 
  {
    printf("%s\n", *next);
    next++;
  }
  return 0;
}</stdlib.h></stdio.h>

If you want to get the value of a specific variable you can use GetEnvironmentVariable()

I had created variable in user section , using the following code

'defining variables
dim objShell, colUserEnvVars

'initializing all variables
Set objShell = WScript.CreateObject("WScript.Shell")
Set colUserEnvVars = objShell.Environment("System")

'Output File for registry information.
colUserEnvVars("rahul") = "rahul"

but i cannot read the same from c++, for this i have to restart the system,

but Wscript.Echo colUserEnvVars("DeloitteAuditShare123") read the value without restarting ths system.

GetEnvironmentVariable( ) will work from VS2005 onwards. Have you tried that.

you may call CMapStringtoString::RemoveAll, but CMapStringtoString destructor does this. you don't want to delete individual elements in this collection. For reference you may check [COLLECT Sample: Illustrates MFC Collection Classes^]
