One simple solution is to create a CLI/Interop DLL compiled with /clr, this DLL can export standard C function, which the C++ code can call.
When implementing the standard C functions in the CLI/Interop DLL , then one is able to call standard .NET code, and it is possible for the CLI/Interop DLL to have references to other standard .NET assemblies.
This example hosts a WinForms control in a MFC application, but one could just aswell host a WPF control:

Then you must be doing something wrong, but we cannot guess what happens in your code without seeing some of it.

Actually i tried
CMenu *pMenuBar = this->GetMenu();
ASSERT_VALID(pMenuBar);
CMenu *pSubMenu = pMenuBar->GetSubMenu(0);
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_1, "First Item");
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_2, "Second Item");
By this i can add.but in the mainmenu already one Exit submenu is there.But i dont want that.
So i deleted that sub menu in resource file itself.And when i gave this code it shows assert error.
If i didnot delete Exit menu ,then after running application my FILE menu shows
FILE
Exit
FirstItem
Second Item

So can you not just remove it from the .rc file?

If i remove this Exit from .RC menu editor.When im runnong application it shows Unhandled Exception error.
So what i did,i coded like
pSubMenu->RemoveMenu(0, MF_BYPOSITION);
This will remove the Exit dynamically and then i added my menu by
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_1, "First Item");
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_2, "Second Item");
Now i want to rename the main menu text dynamically.
I dont know how can i do that?

And that doesn't concern you?

Employing a "band-aid" fix is not the right answer.

How about ModifyMenu()?

You can override OnInitMenuPopup() and insert and remove menu items there.
What is happening is that your menu template (in the .rc file) is being loaded automatically. Until it is loaded, trying to insert or append will have no effect. OnInitMenuPopup() gives you a chance to modify the menu before it is displayed.

What do those two functions return? Have you tried calling ::InsertMenu() or ::AppendMenu() instead?

If the menu is already selected into the mainframe at time of modification, you need to call DrawMenuBar() after updating it for changes to take effect (be shown)

There is a requirement to hide the vertical scrollbar of listbox .

There is a requirement to hide the vertical scrollbar of listbox when items exceed the display area. There is no option to hide vertical scrollbar but there is a option for to hide horizontal scroolbar.

|
|

Can't you remove the 'Verical scroll' style from the list box property, or remove WS_VSCROLL window style?

Hi im haveing CPtrList and im adding this list by gettign data from xlsheet.What happened after adding details to list,the list having the same last data.suppose the list count is 3,then 3 listitems are same data.Here the code
CPtrList GrPageList;
void CGraphConfig::OnImportgraph()
{
CString TempString,TempInfo,sExt;
int PointCount=0,iRow=0;
CString sFileName = _T("");
SGrPgConf *pDetl = new SGrPgConf;
if(pDetl == NULL)
{
AfxMessageBox("Memory Allocation Failure ");
return;
}
GrPageList.RemoveAll();
CFileDialog oFileOpen(1,"xls",0,0,"MicroSoft Excel Files(*.xls)|*.xls|Tag Detail Grid File(*.tdl)|*.tdl||");
oFileOpen.m_ofn.lpstrTitle="Import From...";
if(oFileOpen.DoModal() == IDOK)
sFileName=oFileOpen.GetPathName();
sExt=sFileName.Right(3);
sExt.MakeLower();
if(!strcmp(sExt,"xls"))
{
CExcelSheet TagDet(sFileName,"Sheet1",FALSE);
for(iRow=2;iRow <= TagDet.GetTotalRows();iRow++)
{
TagDet.ReadCell(TempString,1,iRow);
pDetl->iPageNo = atoi(TempString);
TagDet.ReadCell(TempString,2,iRow);
sprintf(pDetl->sPageTitle ,"%s",TempString);
TagDet.ReadCell(TempString,3,iRow);
sprintf(pDetl->sPanelDetail[0] ,"%s",TempString);
TagDet.ReadCell(TempString,4,iRow);
sprintf(pDetl->sPanelDetail[1] ,"%s",TempString);
GrPageList.AddTail(pDetl);
POSITION hPos = GrPageList.GetHeadPosition();
while(hPos)
{
SGrPgConf *pData = (SGrPgConf *)GrPageList.GetAt(hPos);
GrPageList.GetNext(hPos);
}
}
TagDet.Commit();
}
}
When i check the list the pData shows the same data(last row - pageno-3.0) three times,GrPageList count is 3.
My XLSheet shows like
PageNo PageTitle FirstKey SecKey
1.0 graph1 Group01 Group02
2.0 graph2 TREND01 TREND02
3.0 graph3 Group01 Group02
Pls help me..

you are updating the value at the same pointer and adding the same pointer to the CPtrList every time. So all the entries point to same data.
Do SGrPgConf *pDetl = new SGrPgConf; inside the for loop. Remember to delete all entries in list when they are no longer needed.
for(iRow=2;iRow <= TagDet.GetTotalRows();iRow++)
{
SGrPgConf *pDetl = new SGrPgConf;
TagDet.ReadCell(TempString,1,iRow);
pDetl->iPageNo = atoi(TempString);
GrPageList.AddTail(pDetl);
}

In the following function replacing "number - 1" does not yield the same correct result as "--number"? Why is that so? Am I'm missing something?
int sum( int number )
{
int result;
if (number == 1)
return number;
else
{
result = sum(number - 1) + number;
return result;
}
}
|
|

--number changes the value of number, number - 1 does not.
say number is 10:
sum(number - 1) + number; is sum(9) + 10;
and
sum(--number) + number; is sum(9) + 9;
You may be right
I may be crazy

The first line was enough! Thank you very much! Sometimes, well maybe most of the time I'm so stupid. That's so obvious!

Being a bit pedantic here (but it's necessary!)...
Since the order of evaluation is not defined by the language spec, the compiler writer is free to choose, so your second example
sum(--number) + number; could come out either way (but number will always wind up decremented). There are lots of examples of confusion over this.
Cheers,
Peter

I concur, at least for C. I just don't know for recent versions of C++.
And I would never write a statement like that.
