from MSDN

After creating the control, you can change all of the styles except for MCS_DAYSTATE and MCS_MULTISELECT. To change these styles, you will need to destroy the existing control and create a new one that has the desired styles. To retrieve or change any other window styles, use the GetWindowLong and SetWindowLong functions.

I have tried to destroy the control using pMonthCalCtrl->DestroyWindow() in response to the user clicking the dropdown button, however, I get an access violation when i run it, how do you destroy the MonthCalCtrl?

Thanks

Did you ever fix this problem? I am having the same problem in getting bold dates up. If you managed to destroy and recreate the window and get the dates bold I would love to know how.

Hope your still reading.

Thanks

No, I looked absolutely everywhere and tried just about everything but I eventually gave up as I couldn't find a solution anywhere. If I do have any success I will let you know, and could you do the same if you find a solution.

Thanks

Well I worked around it so that I can use it the way I want! Big Grin | :-D

Basically I added an invisible Month Calendar control which I then set to the same space as the DateTimePickers rect in the DropDown handler. I also set a flag for bMonthShowing.

In the OnPaint method I use the bMonthShowing flag to let me know to reposition the windows

m_pMonth->SetWindowPos(&wndNoTopMost, 0, 0, 1, 1, SWP_NOMOVE | SWP_SHOWWINDOW);
m_ctlMonth.SetWindowPos(&wndTopMost, 0, 0, 1, 1, SWP_NOMOVE | SWP_SHOWWINDOW);

In the CloseUp handler I set the MonthCalendar invisible.

For the month calendar I handle the GetDayStates to set which days I want bold.
In the OnSelect for the month calendar I do the following:

COleDateTime t;
SYSTEMTIME tt;
BOOL ret = m_ctlMonth.GetCurSel(&tt);
t.SetDate(tt.wYear, tt.wMonth, tt.wDay);
m_ctlDatePicker.SetTime(t);

(If I did the GetCurSel directly into a COleDateTime it comes back with an invalid status Confused | :confused:

)

And everything works! <edit> All right I missed one or two (or more) things. oops
What a kludge!

If you want I can send you the whole dialog project. Let me know.

I just checked the result of pMonthCalCtrl->GetStyle() before and after the use of the ModifyStyle function and the result is the same. (The ModifyStyle seems to be affecting the wrong style?)

Thanks for all your help so far

I think this should work:

// Get handle to MonthCalendar control
HWND hwndDP = pCalCtrl->GetSafeHwnd();
ASSERT (hwndDP != NULL);
HWND hwndMC = DateTime_GetMonthCal (hwndDP);
ASSERT (hwndMC != NULL);
CWnd* pMCCtrl = CWnd::FromHandle (hwndMC);
ASSERT (pMCCtrl != NULL);

// Set its style
DWORD dwStyle = pMCCtrl->GetStyle();
dwStyle |= MCS_DAYSTATE;
pMCCtrl->SetStyle (dwStyle);

Bitmap Background for CDialog

DanYELL16-Jun-04 9:02

DanYELL

16-Jun-04 9:02

There is cool code here:

http://www.codeproject.com/dialog/bmpdlg01.asp

that shows how to make a bitmap a background for a
CDialog. I have a rather large bitmap, its about 1600x
600 pixels and when I use that bitmap, it looks great
but if I scroll up or down, the images flickers or doubles
up or drags with the scrolling and looks really bad.

Any chance any one has experienced this and has a
resolution? I tried just laying the bitmap in a CDialog
and laying edit boxes on top of the bitmap. But the
edit boxes disappear under the bitmap and Im just perplexed.

Please, any response any one can give me will be greatly
appreciated.

Sincerely,
Danielle (an overworked graduate student)

Just poking around here, this probably won't work... but if your image covers the entire dialog surface try NOT calling the base class CDialog::OnEraseBackground().

hey, the forum is for asking specific programming questions... we cannot guess what you need and what you don't.

ask for something, you'll get an answer (we'll try to...)

for C++, you can have a look at The C++ Language (but it's a book, not a site) from Bjarne Stroustrup, even if it is not for beginners (say Maxwell chen... Big Grin | :-D

chkesp, _chkesp, and ESP ???

I come back from a 2 week break and notice that my code no longer works - I am getting errors related to

i386\chkesp.c<br />
The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.<br />

As I believe nothing has changed with the file(s) going into this build, maybe some compiler settings were changed. I'm at a total loss and need some advice/direction.

Thank you.

I have my files in VSS - since coming back from hiatus, I did a "Get Latest" into clean folders, rebuilt everything and then ran.

My situation can be generalized as follows:

<br />
1) a dialog class that contains some processing (OnOk, etc.)<br />
   CAdjustTimesDlg<br />
<br />
2) CAdjustTimesDlg has a private function (the offender)<br />
   void UpdateTheList(CMyData item1, CMyData item2);<br />
<br />
3) AdjustTimes.cpp has the caller as:<br />
   // some code<br />
   UpdateTheList(item1, item2);<br />
<br />
   // and the function itself<br />
   void CAdjustTimesDlg::UpdateTheList(CMyData item1, CMyData item2)<br />
   {  // the code<br />
   }<br />

I have tried looking at the .DSP (settings), but there was no change. I tried explicitly casting the call as:

<br />
   (void) UpdateTheList ( (CMyData) item1,  (CMyData) item2 );<br />

But nothing I've tried so far has worked. Confused | :confused:

It confuses me because there was no problem in previous builds and executions - I don't see anything that has changed.

Thanks.

I need a help in converting files like .doc, .xls etc to tiff files.

I looked through Word's Save As list and did not see TIFF as an option. That's not to say it cannot be done, but having not ever done this, my initial response is "Is it possible, since Word does not offer such a conversion?"
