Hi,
I have a static CString variable declared in the dll.
static CString strUserName;
After which i make some modification to this CString inside the file. Now, I want to export this value.
However in the .def file of the dll, in EXPORTS i mention only the variable name.
EXPORTS
; Explicit exports can go here
strUserName
But i am getting linker error.
Linking...
AppProject.def: error LNK2001: unresolved external symbol strUserName
Kindly help

Remove the static keyword from declaration. If the varaible is global, then there is no need of static isnt it?

I suspect you also need to declare in the CPP file that the variable will be exported, using __declspec(dllexport).
But I've never actually exported a variable. Always a class, or a function which can modify or retrieve that variable. This gives me room at a later date to change how I work on the variable. Does it exist in the DLL? Do I interrogate some other resource (ie a DCOM object) for it, etc. It gives me more flexibility. Just a style recomendation, not a RULE.

The solution resides in your query itself. See GetSystemTime().
Somethings seem HARD to do, until we know how to do them.

Have a look at COleDateTime too.

// the user checked the box and specified data
CString str;
// is it a time-only control, or a date-only control?
if ((m_retirmentdate.GetStyle() & DTS_TIMEFORMAT) == DTS_TIMEFORMAT)

You're not using the mutithreaded libraries.
- Select "Projects"->"Settings..." from the menu.
- Select the "C++" tab.
- Select "Code Generation" from the "Category" combo.
- In the "Use run-time library" combo select a multithreaded one.

I try to resize my CFrameWnd, but it doesn't work.
Can anyone tell me the reason, thanks
void CMyApp::OnAppAbout()
{
//here I want to resize and draw my framw window
SendMessage(AfxGetMainWnd()->m_hWnd, WM_SIZE, SIZE_RESTORED, MAKELPARAM(50, 50));
AfxGetMainWnd()->ShowWindow(SW_SHOW);
AfxGetMainWnd()->UpdateWindow();
}
|
|
|
|
|
SetWindowPos(AfxGetMainWnd()->m_hWnd,NULL,0,0,50,50,SWP_SHOWWINDOW);
|
|
|
|
|
Thank you for your advise.
If I call SetWindowPos, it indeed does work.
However, I feel very strange about why WM_SIZE message doesn't do any effect.
Won't it redraw the frame after I resize it?

From MSDN:
"The WM_SIZE message is sent to a window after its size has changed. "
Did you mean to call the windows API function MoveWindow() (Or it's MFC wrapper equivalent)?
CWnd* pWnd=AfxGetMainWnd();
if (pWnd) {
CRect rect;
pWnd->GetWindowRect(&rect);
rect.right=rect.left+50;
rect.bottom=rect.top+50;
pWnd->MoveWindow(rect);
}

If you are talking about deployment of your application then you need to read the documentation[^]

Do you know how to check date validation?
I use COleDateTime and at environment without VS7 - it is wrong!!!
Do you know other calss for VC7 to check that? 1900-02-31 - wrong, 1900-02-28 - OK.
Thanks!!!

Several ways exist. There's the COleDateTime class, and functions like mktime().

How so?
TalSt wrote: Do you know other calss for VC7 to check that? 1900-02-31 - wrong,
Are you implying that some functon is stating that 1900-02-31 is a valid date?

Hello,
Our application developed using VC++ with COM. Our new requirement is to launch user written ASP forms from our application. To achieve this I added CWebbrowser2 control in our dialog and launched ASP pages using Navigate method. The problem is that we need to pass some input data to these ASP pages before it diplayed in CwebBrowser. This input is to fill out some fields on ASP form.I tried to pass this by appending input string to URL, but there is 2083 characters limit on URL. Is there anyway I can pass huge input string to ASP? I tried to use PostData parameter in CwebBrowser.Navigate(...) method but no success.
I am also open to any alternative approach for my requirement other than CWebbrowser2 control.
Advance thanks to responders.

That is the way to do it. Don't give up too easily.
SafeArrays are a pain in the behind but a necessity if you want to post data.

Thanks bob for your reply. I built postdata param as follows:
CComVariant postData("MyInput=My Custom Input");
char* postDataString = "MyInput=My Custom Input";
int len = strlen(postDataString);
postData.vt = VT_ARRAY;
postData.parray = SafeArrayCreateVector(VT_UI1, 0, len);
void HUGEP* safeData;
SafeArrayAccessData(postData.parray, &safeData);
memcpy(safeData, postDataString, len);
SafeArrayUnaccessData(postData.parray);
May be i am doing something wrong on ASP side to retrieve this postdata. I am novice in ASP. Can somebody tell me ASP command to retrieve it?
