Hi all,
I made MFC dialog based application under VC 2005. I also made package for it. It runs perfectly on other windows machine. Now I want to deploy this MFC based application on Linux machine. What should i do to accomplish this task? Please help out in this. Any help is highly appreciated

AFAIK, MFC application is not supported on Linux plateform, you might be requiring third party framework to do so like QT etc or wait for other GURU's to comment

You will need to rewrite your application to support Linux's windowing system. MFC is Windows only. There are numerous cross-platform tools to help. If you like MFC, try wxWidgets.

-you may want to take a look at wine and winelib. These can be used to run your application under linux in an emulated win32 environment or to make a port recompiling and linking against winelib. Several windows applications have been "ported" to linux using winelib (google's picasa for example).

Hi all,
I am using ZLib for compression and decompression of files in my code. My problem is code is working fine in xp but when i decompress my files(specially exe files) in vista it gives an error stating Software has stoped working. How to solve this problem.
Thanks in advance

Your attempt to decompress/compress an .exe gives the error, or trying to run the .exe gives the error?
Where are you compressing/decompressing the files to?
Is the compress/decompress being run on the Vista box?
Is UAC turned on? Is File Virtualization active?
Are you an administrator or user?
Are you deleting the old .exe to verify current attempts are generating files? Sometimes, if the file write is failing and there was previous file from a previous test in the directory I'm trying to create it to, it's easy to think the old file is the newly created on from the last attempt.
Are you sure it's Vista or is it because your running it on another machine with a different initial memory at locations of your pointers. Sometimes, if you fail to initialize pointers, and the program is run in the same context on many boxes with the same ghost image, you'll get lucky and the memory that just happens to be lying at the location of a pointer is null, you get by for months until someone runs it on a different context, different box with a different OS, etc...
It's usually time well spent to check your pointer initializations when code seems to work fine on one set of boxes then acts strange on other images or boxes.
Just some thoughts.

I haven't heard of a problem with zlib on Vista, which error code do you get from zlib?

I get the data from file by using this code
<br />
void CSearchDlg::OnFileOpen() <br />
{<br />
CFileDialog fd(TRUE,NULL,NULL,NULL,"Text file|*.txt");<br />
<br />
if (fd.DoModal()==IDOK)<br />
{<br />
<br />
CStdioFile s( fd.GetPathName(),CFile::modeRead);<br />
<br />
s.ReadString(temp);<br />
dat+=temp;<br />
dat+="\n";<br />
<br />
while(!feof(s.m_pStream))<br />
{<br />
s.ReadString(temp);<br />
dat+=temp;<br />
dat+="\n";<br />
}<br />
}<br />
<br />
}<br />
And then I need to extract the data from CString object(that is dat) in each line.
How can I do?
|
|
|
|
|
No native way, I think.
Use the CString member functions to do it manually.
Or replace the method.
|
|
|
|
|
will the following algorithm help you?
while(dat!="")
{
CString line;
line=dat.Left(dat.FindFirst('\n'));
dat=dat.Right(dat.FindFirst('\n'));
}
//if ('\n') doesnot work, then try with (13) or (10)
good luck.
--------------------------------------------
Suggestion to the members:
Please prefix your main thread subject with [SOLVED] if it is solved.
thanks.

OnKeyDown will batch the messages when I keep pressing down a key.
For example, if press down a key,
OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
will combine several conituous keys with increasing nRepCnt.
But I want to refresh the screen without this combination.
Does it mean I'd better use a timer?

Do you want to refresh screen for example after 5 minutes?
|
|
|
|
|
No.
If nRepCnt=10, I want to refresh 10 times, because I when I press the key, a parameter will be changed and the displays will change according to the parameter. I just want to show the user the continous changing. There will be 10 different displays.

If you want it with pauses between the screen updates... yes, the best solution is a timer and a counter to call Invalidate and UpdateWindow.
If you are tracking the changes in diferent displays, and dont need to make it slow... you can call the same functions into a for

Thanks, I will try it if I can't find a better way, a timer is a little expensive.

Maybe with a bit more info... What for a secuence do u want to achieve? Say it in Pseudocode

For example:
1. I draw a circle in the client area
2. Press "up" to increase the radius or press "down" to decrease the radius
3. draw again
I want to show the user continuous changing of the shape of the circle, like 10->9->8->7->6->7->8->...,not like 10->8->4->...

unsigned char* pImg1=new unsigned char[40+120*30];
unsigned char* pImg2=new unsigned char[40+92*30];
unsigned char* pDib1=pImg1+40;
unsigned char* pDib2=pImg2+40;
//int the next codes i give the pDib2 values to pDib1, assume, i have
//given the pImg2 values before
for(int i=0;i<30;i++)

for(int j=0;j<90; )

pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=0;
}
}
delete []pImg1;
delete []pImg2;
when i want to delete the two pointers, there is debug error! i suspect the pImg1 memory space is bigger than its defination, but from the upper loop, the last value is pDib[29*120*90+29]=pDib[2599], the memory spance is just equal to the defination, what the matter?
thanks first

I have tested the code in VC6, no error.
Consider whether you used the memory after the delocation.
|
|
|
|
|
Your illegal access is where j is reaching 90 when i is 30, the array bounds are 120*30, not 120*30 + 90 for pDib1, so "+ j" is taking you outside of the array.
Is this code doing what you want? The k variable here is redundant.
...
int k=0; // k = 0
for(int j=0;j<90; ) // k not modified
{
pDib1[i*120+j+k]=pDib2[i*92+j++]; // k not modified
pDib1[i*120+j+k]=pDib2[i*92+j++]; // etc...
pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=0;
}
Also, a much better way to access an array like this is to increment to vars by 120 and 92 for each loop with i, saves the continual multiplication by constants, a slow down which dwarfs any speed benefit you gain from putting your increment inside the index. Consider:
int a=0, b=0;
for(int i=0;i<30;++i)
{
for(int j=0;j<90;j+=3)
{
pDib1[a+j]=pDib2[b+j];
pDib1[a+j]=pDib2[b+j+1];
pDib1[a+j]=pDib2[b+j+2];
pDib1[a+j]=0;
}
a+=120;
b+=92;
}
This is faster and more legible (and still broken!).
Hope this helps.

thanks Jheriko++:
it was my fault that i forgot writting a code line:
int k=0;
for(int j=0;j<90; ) {
pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=pDib2[i*92+j++];
pDib1[i*120+j+k]=0;
k++;// k is modified here!
}
my expectiong is that:
//first loop
pDib1[0]=pDib2[0];
pDib1[1]=pDib2[1];
pDib1[2]=pDib2[2];
pDib1[3]=0;
//secont loop
pDib1[4]=pDib2[3];
pDib1[5]=pDib2[4];
pDib1[6]=pDib2[5];
pDib1[7]=0;
//the third loop
pDib1[8]=pDib2[6];
pDib1[9]=pDib2[7];
pDib1[10]=pDib2[8];
