Do you have #include<iostream.h> in your code ? If yes, try #include<iostream> instead.

I had asked to remove iostream.h include, and put <iostream> instead. Try that out. The other possibility is you are not able to link with msvcprtd.lib. Check whether the path for msvcprtd.lib is included into the project settings. Search for the lib, and make sure the paths are there in include directory.
Probably
\Program Files\Microsoft Visual Studio 8\VC\lib
\Program Files\Microsoft Platform SDK\ (SDK Folder)
for AMD64.
|
|
|
|

Seems you're application is targeted to run under 64-bit environment.
Please put $:\Program Files\Microsoft SDK\Lib\IA64 (AMD64) in the top of lib directories. (Tools->Options->VC++ Directories).

Thankx Sarath
after Changing the settings as u said i got the following error
LINK : warning LNK4076: invalid incremental status file '.\Debug/eSLogOn.ilk'; linking nonincrementally
version.lib(VERSION.dll) : fatal error LNK1112: module machine type 'IA64' conflicts with target machine type 'x64'

Try the other folder amd64. In my understanding x86 actually renamed to AMD64.

I am currently trying to get the bitarray of bitmap that has already been loaded into a picture box of a dialog window when I press a button on the dialog.
The overall aim is, Button 1 takes data from user, takes editing parameters and creates a BMP from it the result of the editing , putting the BMP into a picture box in a dialog. Button 2 is the "save" feature, which allows the final changed Bitmap to be saved back into bitmapbits array.
Here's the problem:
void CProjectDlg::OnButton2Press()
{
CFile TestFile;
HBITMAP CapturedBMP = m_PicBox.GetBitmap();
CBitmap RS232BMP;
RS232BMP.Attach(CapturedBMP);
BITMAP TempBMStore;
RS232BMP.GetBitmap(&TempBMStore);
BYTE* bmpBuffer=(BYTE*)GlobalAlloc(GPTR, TempBMStore.bmWidthBytes*TempBMStore.bmHeight);
DWORD dwValue=RS232BMP.GetBitmapBits(TempBMStore.bmWidthBytes*TempBMStore.bmHeight, bmpBuffer);
}
I get a valid handle at (1) but I my TempBMStore is blank after I execute line (2), meaning I do not have a valid Bitmap or something (return value is 0). What Am I doing wrong here?
When I cut and paste this code into the section of code that originally places the bitmap into the picture box, I have absolutely no problem. ie:
void CProjectDlg::OnButton1Press()
{
.
.
.
<get data="" from="" user="">
.
.
.
<edit the="" bitmap="" bit="" values="">
.
.
.
m_PicBox.SetBitmap(TmpBmp);
CFile TestFile;
HBITMAP CapturedBMP = m_PicBox.GetBitmap();
CBitmap RS232BMP;
RS232BMP.Attach(CapturedBMP);
BITMAP TempBMStore;
RS232BMP.GetBitmap(&TempBMStore);
BYTE* bmpBuffer=(BYTE*)GlobalAlloc(GPTR, TempBMStore.bmWidthBytes*TempBMStore.bmHeight);
DWORD dwValue=RS232BMP.GetBitmapBits(TempBMStore.bmWidthBytes*TempBMStore.bmHeight, bmpBuffer);
}<pre>
Thje return for line (2) is valid and I can get the bitmap bits with no errors. Same code, different behaviour. Do I need to make the Picture Box valid or something?
Thanks in advance

|

Is it possible that TmpBmp in your OnButton1Press is a local variable and when the method returns it destroys the bitmap so when you later try to access it you get an invalid handle? (CBitmap's destructor destroys the bitmap associated with it)

Never thought of it that way. Thought the Picture box would store the data so I can retrieve it later or allow another function to operate on it.
If the data object is destroyed like that, all my functions would have to be tightly coupled together. and that would be rather wierd from an OO programming POV.
You have anyway to retrieve a bitmap from a picture box object in a dialog AFTER the function that places it there destroys the CDC that was containing it?

Well, make your CBitmap a member variable of your dialog class, then the bitmap will be existent while your dialog is up, or you could use the Detach method to "disconnect" the CBitmap and the HBITMAP but i don't know if the image control is possible to destroy the bitmap for you, pay attention or you could leak GDI resources.

Dear all,
How can I tell c++ to allocate memory from Physical RAM, not virtual memory (on WinXP).
Thanks in advance,

Can you more explain what do you need exatcly?

Thanks a lot 4 ur excellent answer  .

what is the meaning of '?'and ':' in this expression?
bool Addr
int m= Addr ? 1 : 5
thanks
|
|
|
|
|
means:
int m;
if (Addr)
{
m = 1;
}
else
{
m = 5;
}
check Addr (? -> check)
if its true use first expression (1)
else use second one (5)
|
|
|
|
|
X1 ? answer1 : answer2
If X1 is true the expression will return answer1, if it is not it will return answer2 and I think you are new so see C++ Reference[^].

|
|
|
|
|
This line of code first evaluates the condition 'Addr == true'.
Then, if the condition is true assigns 1 to m, otherwise asssigns 5 to it.

the ?: is a ternary operator(takes three operands), which is known as Conditional Operator. Its the simplified form of a simple if statement. Check the MSDN Link[^] for more info.

I'll guess you may have to write a program to do that, without regards to what version of Visual C++ you are using.
A little more clarity on your query, may be?

Hey there,
I am using a CProgressBar to show the progress of several checksum operations. There are 3 of them, md5, sha1, and sha2, and they are done sequentially. I want to reset the progress bar just before each calculation, but I can't get the progress bar to redraw. Here is a snippet of what I am trying to do:
if(m_checksumPPage.isMD5Checked()) {
progbar.Invalidate();
progbar.UpdateWindow();
progbar.SetPos(0);
hash.domd5(progbar);// do the hash, which also updates the progbar to 100
}
if(m_checksumPPage.isSHA1Checked()) {
mprogbar.Invalidate();
progbar.UpdateWindow();
progbar.SetPos(0);
hash.dosha1(progbar);// do the hash, which also updates the progbar to 100
}
if(m_checksumPPage.isSHA256hecked()) {
progbar.SetPos(0);
progbar.Invalidate();
progbar.UpdateWindow();
hashsha2.do(progbar);
}
The hash.doxxx(progbar) methods will increment the progbar from 0 to 100 and leave it there when it finishes. The first time through it works fine, but the attempt to reset the progbar to zero for the second and third pass does not move the bar back to zero. I guess I am leaving out some sort of update message someplace, but I can't figure it out.
The progress bar is a CProgressCtrl and it is on a dialog box.
Any ideas?
Paul
