You need to create a CButton member control variable. If you are using VS6, use ClassWizard (Ctrl+W). If you are using VS20xx, right-click the control and select Add Variable from the context menu. Now just use the SetWindowText() method of the member control variable.

Hi David,

thanks for your suggested further reading. For now, it is quite a bit beyond

take a closer look at the article.

Is CListView removed from Visual Studio 2005 Pro? When I was going to use it in a MFC project, I got the error:
error C2065: 'CListView' : undeclared identifier

Hi
we are using CPictureHolder in order to display image through data. This data nothing but CString.
we are doing the dcode(converting into byte) and creating the byte into CMemfile object.
The problem is few image data not displaying the image.
i am using below code.
hr = ::OleLoadPicture(lpStream,
maxLen,
FALSE,
IID_IPicture,
(LPVOID*)&m_pPict);

hr return as E_FAIL for some image data.

please let me know what could be reason.

Regards
Gopal

From documentation:

This function returns S_OK on success. Other possible values include the following.

Return code	description
E_NOINTERFACE	The object does not support the specified interface.
E_POINTER	The stream is not valid. For example, it may be NULL.

So what's the actual return value you got?

That's in sharp contrast with the documentation. What is the numerical value?

Probelm with std::ma find function

Hello everyone,
I am using std::map<cstring, cmystruct=""> in my application. I am searching for CMyStruct based on the CString using find function. But sometimes find function is returning null iterator even when there is strcture obj with specified key.
Can anyone help me in finding the solution?

Hi,
here is how I used
std::map<cstring, cmystruct="">mapVar;

void Myfun1()
{
...
CString strTemp = "str1";
mapVar[strTemp] = myStructObj1;
}

void MyFun2()
{
map<CString, CMyStruct>::const_iterator itr;
Cstring strTemp = "str1";
itr = mapVar.find(strTemp);
....
}

Sometimes it is working fine but sometimes it is not working.

Umm, that's odd.
If the key doesn't exist in the sequence std::map::find() returns end() and not NULL.

Have you verified that you haven't added a NULL pointer for the key you're looking for? If the answer to this question is 'no', don't bother answering the following. Wink | ;-)

How have you declared your map? Post some code (preferrably properly formatted using <pre></pre> tags)
How do you add elements to the sequence? (Code again)
