It looks like pPopupMenu is not setup properly prior to the call to OnInitMenuPopup. I tried executing the following command...
pPopupMenu->GetMenuState(0,MF_BYPOSITION);
and it also results in an access violation.
Oh Well.
An Ideas?

Add a handler for WM_KICKIDLE. In the handler, call UpdateDialogControls(this, false); You'll need to #include <afxpriv.h> for the definition of WM_KICKIDLE

Seems like a losing battle... The ON_UPDATE_COMMAND_UI message handler is still never called.
Oh well.

Look for 'Q242577' in MSDN, there is an example 80 lines of code overriding the OnInitMenuPopup function and it worked for me.

I am working on a project where I need to set the region of numerous windows not owned by my application. This works great on 2000 but in testing on a 98se box, I found it gives an "invalid parameter" error(87) when the winow handle passed into setwindowrgn is no associatd with the application calling the function. I cannot find any documentation from MS that eludes to the fact this is not allowed and only occurs on 9x boxes. Does anyone know of a workaround or way to correct this issue. To test - create an app that sets a window region and use FindWindow to get the handle of a running instance of Notepad and try to change the shape of notepad. Keep in mind this works fine on 2000 but not on my 98se machine.
Thanks in Advance.....

Hi all,
I am trying to port a VB application (Playwave.exe) that can be downloaded from the microsoft website to C++. I am basically done, but there is just one small thing:
The GDI routine in VB calls a function called
Line (lastX, leftYOffset + lastLeftY)-(x, curLeftY + leftYOffset)
I translated it to C++ as follows:
pDc->MoveTo(lastX, leftYOffset + lastLeftY);
pDc->LineTo(x, curLeftY + leftYOffset);
However, the outputs that I get are quite different. The VB call paints the wave as a filled polygon while I get a bunch of interconnected lines, of course. Is there an equivalant to this Line function in C++. The Line method is defined as in MSDN:
I tried using methods like Polygon and Polyline but to no avail. BTW: i am not using MFC. Since, I am still in the learning stage, I thought it would be nice to be comfortable with core WINAPI and get a hang of how things work behind the scenes.
Syntax
object.Line [Step] (x1, y1) [Step] - (x2, y2), [color], [B][F]
You can also download the Playwave.exe from
http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B182983[^]
Thanks for any help that you might give me.

Hello !!
I have a Problem:
I have an MDI Application, and I split the Child- windows into 2 Views.
These I do in the PreCreateClient () - Funktion from CChildWnd . I habe a static Splitter with 2 columnes and 2 Views. Now I want to switch the second view away, that only the first view is visible.
Normally I must destroy the child window and then I create it without splitter.
But I want by Programm (not by user) switch the second view away without destroying the child window. Can I make the second view not destroying, only the client- area make it to CRect (0,0) ??
Thank you for helping me

Cany anyone comment on why some people will use:
<br />
int main(int argc, char** argv){}<br />
compared to the MFC app-wizard generated:
<br />
int main(int argc, char* argv[]){}<br />
Thanks.

Imho, the latter is more correct since argv is an array of pointers to characters. Since an array can be looked upon as a pointer to a block of memory that contains a number of fixed size objects (4 bytes, in the case of argv), you could define argv as a pointer to a pointer of characters. The latter definition provides more information.

You will find the first one more common in Unix apps and Win32 ports of Unix apps.
If you are looking for a way to process command-line arguments (even in an MFC app), see my article XGetOpt.

I'm trying to make a list of thumbnails in a listview window. So far I can only make it work with resource bitmaps, when i try a hard coded jpg, i get get a blank image, with "hiya" under it
Its probally something really dumb, but i just cant find it. If anyone could point it out i'd be very grateful
(I'm almost positive its not the Bmp variable, the function does return a BITMAP)
//Here's the code
//Opens a thumbnail struc and sets its x and y
thumb = openThumb(&x ,&y);
_bstr_t txt("Hiya");
//Gets Handle to the listControl
hThumbList = GetDlgItem(g_hWnd ,IDC_LIST_THUMB);
//x = 160, y = 120
hImageList = ImageList_Create(x,y,ILC_MASK | ILC_COLOR32,0,0);
Bmp = getThumbBmp(g_hWnd,hPicDC); //Returns a HBITMAP
//Adds bitmap to the list as position 0
ImageList_Add(hImageList, Bmp, NULL);
SendDlgItemMessage(g_hWnd,IDC_LIST_THUMB,LVM_SETIMAGELIST,0,(LPARAM)hImageList);
lvi.mask = TVIF_TEXT | TVIF_IMAGE;
lvi.pszText = txt;
lvi.iImage = 0; //First Image added
// Insert info to the Listview
SendMessage(hThumbList ,LVM_INSERTITEM,0,(LPARAM)&lvi);

simple, imageList doesn't support jpeg compressed images. only raw bitmaps.
try using GDI+ to load the jpeg and then get an HBITMAP from it.

I have written a COM component in VC++ that connects to a ODBC (.mdb file) through OLE DB. When i try to use it in .asp page i get error (0x80004005 - unspecified error). The same component (same asp file) works fine with PWS under Win98. When i run the same with IIS5 in Win2000 and WinXP i get error. I couldn't find out what might be the problem. Can you help me out?
Thanx in advance

That's because the connection string is different. The ADO/OLEDB section from the ASP documentation shows exactly what it expects.
PWS is a stripped down version of IIS and works with less stringent constraints. That's why it works with PWS.

Thanx Rod,
Actually i created the OLE DB connection using the 'Data Consumer ATL'. I look at it and try to fix it. Thanx once again.

Hi guys
i'm trying to get a listview full of thumbnails to load. kinda exactly like this tutorial:
http://www.codeproject.com/listctrl/thumbnailview.asp
only problem is, theres no source code provided, and i can't figure out what type his "m_imageList" class is
is it some kind of MFC listcontrol class? i can't use any stdfx stuff in my program, so if it is i'm screwd... if not where can i DL the code for the class
any help (soon) would be greatly appriciated!

Hi.
Can anyone explain to me once and for all why do i see people write something like:
if (0==myVar)
{
...
}
instead of:
if (myVar==0)
{
...
}
what difference does it make ?
|
|
|
|
|
Simple. Your compiler will tell you if you type
if (0 = myVar)
whereas
if (myVar = 0 )
will compile and will always set myVar to 0 and evaluate to true.
