Hi,
Any similar problems and/or solutions would be gratefully received!
I've got a setup (msi) made with Installer 1.1 that comes with VS6.
It works like a charm if I log in and install as administrator, but after installation when I try logging in as another user no start menu items (program group, or icons) appear in the start menu.
As well as that, on a client's machine, when other users (IE not Administrator) try our program it completely flakes out; they keep getting 'unsupported operation' when running through the program. We use both ADO as well as flexgrid, but MDAC 2.6 and the FlexGrid files are all installed.
I should note all the machines are Win2k sp3 (the client's are brand new).
Cheers,
Paul

Hello,
I think some of you problems could be in the install program.. When the install package creates the shortcuts all short cuts should be put into the "All Users" profile instead of the "Administrator" or currently logged in profile. 2nd.. If your install package needs to write to the system32 directory you will have to run the install as a admin (no way around it) its the same with all other apps..
Hope this helps

Hi, I'm sorry but this might be a long description. It's about the only way I can explain what is happening.
I've been trying to crop a piece from one bmp file to put into another with an MFC app. The thing is I'm really new to programming, and don't know how to do very much. I've tried a few examples on here, which I didn't get to work because they all seem to use the sceen as a display. I need this to be done behind the scene. I've been trying to learn about DC's but again all the examples I've run into are for the monitor. haha so you see my dilema.
Anyway, what I've come up with is reading in the bmp using a CFile and malloc some memory for it. Then I read out the BITMAPFILEHEADER, and BITMAPINFO. Which I write to the new file. Then from my understanding, the data that follows should be the actual pixels for the image. So to test this I reverse the bits and then write the reversed bits into the new bmp. In theory this should result in an upside down image. It does but, the colors are totally distorted. This is what is confusing me. Am I missing the color palette? Or am I not reading the RGBQUAD correctly? Any help with this would really be appreciated.
Here's my code, maybe you can see where my problem is. Thanks.
<br />
<br />
CFile dibFile(_T("BITMAP1.bmp"), CFile::modeRead);<br />
<br />
<br />
<br />
<br />
BITMAPFILEHEADER bmpFileHead;<br />
<br />
<br />
if(!dibFile.Read((void*)&bmpFileHead, sizeof(BITMAPFILEHEADER)))<br />
AfxMessageBox("Read failed.");<br />
<br />
<br />
<br />
if(bmpFileHead.bfType == ((WORD) ('M' << 8) | 'B'))<br />
{<br />
<br />
DWORD fileLength = dibFile.GetLength();<br />
<br />
<br />
DWORD size = fileLength - sizeof(BITMAPFILEHEADER);<br />
<br />
<br />
BYTE* pDib = (BYTE*)malloc(size);<br />
if(!pDib)<br />
AfxMessageBox("Allocation failed");<br />
<br />
BYTE* pTest = (BYTE*)malloc(size);<br />
if(!pTest)<br />
AfxMessageBox("Allocation failed");<br />
<br />
<br />
dibFile.Read((void*)pDib, size);<br />
dibFile.Close();<br />
<br />
<br />
<br />
BITMAPINFO* pBmpInfo = (BITMAPINFO*)pDib;<br />
<br />
<br />
<br />
BITMAPINFOHEADER* pBmpInfoHead = (BITMAPINFOHEADER*) pDib;<br />
<br />
<br />
<br />
RGBQUAD* pRGB = (RGBQUAD*)(pDib + pBmpInfoHead->biSize);<br />
<br />
<br />
<br />
int s = 0;<br />
for(unsigned g = 44;g < size;g++)<br />
{<br />
pTest[s] = pDib[g];<br />
s++;<br />
}<br />
CFile wFile(_T("test.bmp"), CFile::modeWrite | CFile::modeCreate | CFile::typeBinary);<br />
<br />
wFile.Write((void*)&bmpFileHead, sizeof(BITMAPFILEHEADER));<br />
<br />
wFile.Write((void*)pDib, sizeof(BITMAPINFO));<br />
<br />
wFile.Write((void*)pTest, size);<br />
<br />
wFile.Close();<br />
<br />
<br />
free(pTest);<br />
free(pDib);<br />
}<br />

For an paletted bitmap, you have to use the CPalette classes. There are articles around her and on MSDN do to that.

What you need to do is use a MemoryDC. A memory DC is simply located in memory. You will need to use a DC because that is how you manipulate bitmaps in windows.
First load the image into a CBitmap object with ::LoadImage(...).
Then you will need to create a MemoryDC, however in order to create a memory DC, you first need to have a DC to a window in order to properly set the color bits. If you are going to display this to a particular window, then use GetDC(hwnd) for the window that you will use, or you can use GetDC(NULL) to get the Desktop DC.
if you have a handle to your window hwnd, this is how you would create your memory DC and associate the bitmap with your DC.
<br />
CWindowDC dc(hwnd);<br />
CDC memDC;<br />
memDC.CreateCompatibleDC(dc);<br />
<br />
CBitmap bmp;<br />
bmp.LoadBitmap("C:\\winnt\\bubbles.bmp");<br />
<br />
memDC.SelectObject(bmp);<br />
At this point you will have your bitmap selected into a memory DC and you can start manipulating it. If you want to paste all or just a portion of this bitmap to a window then you can use the BitBlt function of the CDC class.
If you want to create another bitmap that is a cropped portion of your original image, you will first need to create a second Memory DC ans select a bitmap into it that is the size that you desire.
<br />
CDC memCropDC;<br />
memCropDC.CreateCompatibleDC(memDC);<br />
BITMAP bm;<br />
bmp.GetBitmap(&bm);<br />
bm.bmWidth = bm.bmWidth / 2;<br />
<br />
CBitmap bmpCrop;<br />
bmpCrop.CreateBitmapIndirect(&bm);<br />
memCropDC.SelectObject(bmpCrop);<br />
Now you can use bit blt to copy a small portion of the original bitmap into the new smaller cropped image. Here are three examples of how you can copy the bitmap.
<br />
memCropDC.BitBlt(0, 0, bm.bmWidth, bm.bmheight, &memDC, 0, 0, SRCCOPY);<br />
memCropDC.BitBlt(0, 0, bm.bmWidth, bm.bmheight, &memDC, bm.bmWidth, 0, SRCCOPY);<br />
memCropDC.BitBlt(0, 0, bm.bmWidth, bm.bmheight, &memDC, bm.bmWidth / 2, 0, SRCCOPY);<br />
If you look on code project there should be a few examples of how to manipulate bitmaps with memory DCs.
Good Luck

Hey thanks for the quick response. I really appreciate it. I had tried similar code to this. But I couldn't figure out how to get the memDC back into a file. I'm thinking I'll have to use ::CreateFile() and ::WriteFile(). Anyway, thanks again.

I did a quick search (Christian Graus would be so proud!) before posting, to see if anyone had a similar problem as me, and looks like Mike did!
What I'm doing is loading a bitmap from a file, then creating CBitmaps from parts of the file, then using them on buttons. The bitmap file I'm looking is a long strip of images (kind of like an array of images).
It's probably easier to understand if you read the code:
xOffset is the index of the image I want (kBitmapHeight/Wdith are 16 (the size of each image)).
CBitmap temp;
GetBitmapFromResource("c:\\mybitmap.bmp", 0, 0, temp);
m_cMyButton.SetBitmap(temp);
GetBitmapFromResource("c:\\mybitmap.bmp", 1, 0, temp);
m_cMyButton2.SetBitmap(temp);
/
*static*/ bool GetBitmapFromResource(const CString& filename, const int xOffset, const int yOffset, CBitmap &bitmap)
{
CBitmap sourceCBitmap;
bool status = true;
HBITMAP hBmp = (HBITMAP)::LoadImage(AfxGetInstanceHandle(), filename, IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE);
status = sourceCBitmap.Attach(hBmp);
if (!status) {
TRACE0("Failure to load bitmap.\n");
return false;
}
BITMAP sourceBitmap;
sourceCBitmap.GetBitmap(&sourceBitmap);
sourceBitmap.bmHeight = kBitmapHeight;
sourceBitmap.bmWidth = kBitmapWidth;
if (bitmap.m_hObject != NULL) {
bitmap.Detach();
}
status = (bitmap.CreateBitmapIndirect(&sourceBitmap) != 0);
if (!status) {
TRACE0("Failure to create indirect bitmap for source.\n");
return false;
}
CDC sourceCDC;
status = (sourceCDC.CreateCompatibleDC(NULL) != 0 );
if (status) {
void* gdiObject1 = sourceCDC.SelectObject(sourceCBitmap);
CDC targetCDC;
status = (targetCDC.CreateCompatibleDC(NULL) != 0);
if (status) {
void* gdiObject2 = targetCDC.SelectObject(bitmap);
status = (targetCDC.BitBlt(0, 0, kBitmapWidth, kBitmapHeight, &sourceCDC,
xOffset * kBitmapWidth, yOffset * kBitmapHeight, SRCCOPY) != 0);
targetCDC.SelectObject(gdiObject2);
} else {
TRACE0("Failure to create DC for target.\n");
}
sourceCDC.SelectObject(gdiObject1);
} else {
TRACE0("Failure to create DC for source.\n");
}
return status;
}
As you can see, my code is similar to yours.
After calling this with xOffset as 0 and 1, the image of the button is the same (the first image in the file).
However, if I add the bitmap as a resource of my exe, and then load it with
status = (sourceCBitmap.LoadBitmap(resourceID) != 0);
instead of
HBITMAP hBmp = (HBITMAP)::LoadImage(AfxGetInstanceHandle(), filename, IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE);<br />
status = sourceCBitmap.Attach(hBmp);
then everything works (the first button is used for xOffset = 0, the second for xOffset = 1, etc).
The problem is that the bitmap file I'm loading can't be an internal resource: it has to be an external file.
Any ideas on what I need to do to fix this?? It's been bugging me!!
Thanks very much!

I've got an app that I'm trying to create an installation for but am confused with what DLL's to use/register. Does every DLL have to be registered? I mean if I replace a DLL with a newer version does the new one have to be registered and/or do I have to unregister the old one before replacing it? I'm having problems.
My development machine has Win2K on it but if I deliver the Windows 2000 versions of wsock32.dll (winsock) and ws2_32.dll on a Win98 system, either my application or some other Winsock application won't work.
Where do I get dlls that are either a) the latest and greatest for that operating system or b) are 100% compatible for all Win32 operating systems and c) does that even exist?
I know my setup program can be modified to detect OS and I can configure it so that it will install the proper DLLs per operating system but where do I get them? Is it proper procedure to just copy them from a Win98 machine, a Win2000 machine and a WinME machine? And, if I do that am I asking for trouble later on?
Any help, please?

A trick:
if you see the dll file properties, in the tab version you can see in the item name several items, if in the list of thouse, you see a item named OleSelfRegister, you MUST to register the file, if you don't see that item, you only need to copy the file, without register it...;)
Cheers, and good instalation

winsocks is distributed by MS as a zip-OS dependent package. Can't remember the exact url right now.
Now that XP is out, you should also pay attention to what's known as merge modules (.msm files). Those are packages redistributed by MS (see MSDEV.NET cd), which are part of the final .msi setup, which is supposed to be now the only way to properly install software on XP+ OSes.

Wow! How's a guy supposed to keep track of all of this? I'll look on Microsoft for that zip file. Thanks.

Your installation should vary by OS. It should also check if existing DLLs have higher versions and dates and copy your DLL only if your DLL has newer date and higher version. Most DLLs should be backward compatible, i.e., older programs should work. But remember I said "Should be". 
Most OS DLLs should be redistributable. If you application has componments that you bought then you need to read up the licence agreements to see if the DLLs that support those components are distributable.
>Where do I get dlls that are either a) the latest and greatest for that operating system or b) are 100% compatible for all Win32 operating systems and c) does that even exist?
If you find the answer to this question, please let me know. But a good place is usually your own machine if you have the latest Service Packs. I am not sure about XP and the rest of the world. Most DLLs work fine with 98, 2000, and NT. Do not know what happens with XP or if XP DLLs are moved to the others.
Here is one of my nightmares that I have yet to investigate. A Windows Media Player Visualization that I created on Win 98 using VC++ 6.0 works on XP, but the same code compiled on 2000 using VS .Net does not work on XP. Go figure.
I know I did not answer your questions...but I got to rant and let of some steam.

Thanks. I guess getting them off our machines is what we'll do. I was hoping there was one place on Microsoft or a redist directory somewhere to get all of this from.

If you are working on a real world project, I guess someone in your company can get you what you needs. (of course, you have some form of MS product support to play with, don't you?)
Otherwise, for sharewares or the like, here is a link for the win95 redistribuable[^]. Not needed on Windows98 (already installed IMHO).

Well, we have/had MSDN till Jan of 02' and since we're not using .Net, I didn't think we should resubscribe since I heard that MSDN is not updating the non-.net portions anymore.

Chances are, the version compiled with VS.NET uses the MFC7 DLL's. Contrary to what you might think, XP does not come with the .NET framework or the MFC7 DLL's. I believe the XP service pack 1 installs the .NET runtime and the MFC7 DLL's.

MSDN:
-----
CWnd::DestroyWindow
Destroys the Windows window attached to the CWnd object. The DestroyWindow member function sends appropriate messages to the window to deactivate it and remove the input focus. It also destroys the window’s menu, flushes the application queue, destroys outstanding timers, removes Clipboard ownership, and breaks the Clipboard-viewer chain if CWnd is at the top of the viewer chain. It sends WM_DESTROY and WM_NCDESTROY messages to the window. It does not destroy the CWnd object.
....
The DestroyWindow member function also destroys modeless dialog boxes created by CDialog::Create.

yes, but destroywindow is showing up in the DoModal() which makes me think that the dialog should vanish when DoModal is called, after first showing itself? MAy be I'm hopelessly confused ?(I am , I am )
