Thanks a lot Sudden disappearing of VC Console application ramakrishna_s20-Nov-03 20:32 ramakrishna_s 20-Nov-03 20:32  Hi, Please help me regarding one serious problem in our applications observed recently. We have developped a VC++ Console based application with windows socket programming and MSMQ's with Multi threading (Using MFC). It will connect to a server through TCP/IP before start processing and it is a gateway kind of application which need to run for months with lot of load. The problem we are facing is some times the application is disappearing with out any notification. Till now we observed that out of 3 instances of the same application running on the same machine, One instance got disappeared We have incorporated ErrorLogging and Try-Catch mechanisms also But did n't observe any useful log. I would like to know under what circumstances such an application can disappear. Thanks in advance Rams Re: Sudden disappearing of VC Console application Prakash Nadar20-Nov-03 23:37 Prakash Nadar 20-Nov-03 23:37  May be it is terminated due to memory leakes.

Prakash Nadar20-Nov-03 23:39 Prakash Nadar 20-Nov-03 23:39  First of all you wont have that famouse window in the release build. To catch all the errors and simple get out, you can do this. put a try catch around the message pump, and in the catch terminate the program Regards, Prakash.

Patje21-Nov-03 4:05 Patje 21-Nov-03 4:05  Last summer we had similar problems. Finally I bought the book "Debugging Applications for Microsoft .Net and Microsoft Windows", written by John Robbins. You should find this at Amazon. Also take a look at the www.wintellect.com[^] website, the employer of John Robbins, a company specialized in debugging. Also take a look at the CodeProject articles in the Debug Tips section (http://www.codeproject.com/debug/[^]). Some of the articles mention how to catch application crashes.

Are requests being sent to your IP? Then this is pretty easy: extract the request header from the begining of the data.

Now i am saving the data as follows: BITMAPFILEHEADER hdr; LPBITMAPINFOHEADER lpbi; CFile file; if( !file.Open( the_filename, CFile::modeWrite|CFile::modeCreate) ) return FALSE; lpbi = (LPBITMAPINFOHEADER)m_pFirstBuffer ; lpbi->biBitCount=24; int nColors = 1 << 24; if(nColors> 256) nColors=0; lpbi->biClrUsed=0; lpbi->biSize=40; lpbi->biHeight =(DWORD)bmp.bmHeight; lpbi->biWidth=(DWORD)bmp.bmWidth ; lpbi->biXPelsPerMeter =lpbi->biYPelsPerMeter =0; lpbi->biClrImportant =0; lpbi->biPlanes =1; lpbi->biCompression =0; lpbi->biSizeImage = bmp.bmHeight *bmp.bmWidthBytes ; // Fill in the fields of the file header hdr.bfType = ((WORD) ('M' << 8) | 'B'); // is always "BM" hdr.bfSize = (DWORD) (sizeof(BITMAPFILEHEADER) + lpbi->biSize + lpbi->biClrUsed* sizeof(RGBQUAD) + lpbi->biSizeImage); hdr.bfReserved1 = 0; hdr.bfReserved2 = 0; if (lpbi->biBitCount > 0 && lpbi->biBitCount <= 8) { hdr.bfOffBits = (DWORD)(sizeof(hdr) + lpbi->biSize +nColors * sizeof(RGBQUAD)); } else { unsigned long cmapsize = 0; switch (lpbi->biBitCount) { case 16: case 32: if (lpbi->biCompression == BI_BITFIELDS) { cmapsize = 3*sizeof(DWORD); } break; case 24: cmapsize = lpbi->biClrUsed*sizeof(RGBQUAD); break; default: // no colormap break; } hdr.bfOffBits = (DWORD)(sizeof(hdr) + lpbi->biSize + cmapsize); } // Write the file header file.Write( &hdr, sizeof(hdr) ); // Write the DIB header and the bits file.Write( lpbi, lpbi->biSize ); file.Write( m_pFirstBuffer, bmp.bmHeight *bmp.bmWidthBytes ); file.Close (); Now i could open the saved file in Windows Paint application but if i call LoadImage() with that file name as parameter it returns NULL. GetLastError() is zero. Could anyone tell me where i am wrong? Regards Neha Re: GetBItmapBits() Abhishek Srivastava21-Nov-03 0:09 Abhishek Srivastava 21-Nov-03 0:09  Hi Neha, Actually , While saving the BITMAP u converted it into Device independent Bitmap.and LoadImage API cannot load DIB's , it can load only icon, cursor, animated cursor, or bitmap or OEM Bitmaps. If u want to display this Bitmap, then u have to read the file by your own code ,get the BMP data in a buffer prepare headers, and u can use APIs like DrawDibDraw to draw ur image Regards Abhishek Abhishek Srivastava Software Engg (VC++) India ,Noida Mobile no 9891492921 Re: GetBItmapBits() Neha21-Nov-03 0:48 Neha 21-Nov-03 0:48  I think you got confussed. I am using GetBitmapBits() it returns device dependent bitmap. In LoadImage() i am setting LOADFROMFILE. this will returns us the HBITMAP.I mean to say the value returned from LoadImage() ie HBITMAP is NULL. Re: GetBItmapBits() Abhishek Srivastava21-Nov-03 1:02 Abhishek Srivastava 21-Nov-03 1:02  // Write the DIB header and the bits file.Write( lpbi, lpbi->biSize ); check these above line of ur code In ur Submitted code , u have created this DIB header, Which states that the BMP u created is DIB,and let me know if u the file extension is .bmp then that means u have created an DIB image , thats why LoadImage fails. Check few artilces for .bmp files , u can see these Windows supported Picture files are Device independent. Even if u used the GetBitmapBits , but while saving u converted it into DIB Regards Abhishek http://www.prepressure.com/formats/bmp/fileformat.htm Abhishek Srivastava Software Engg (VC++) India ,Noida Mobile no 9891492921 Re: GetBItmapBits() Neha21-Nov-03 1:10 Neha 21-Nov-03 1:10  My file extension is .DIB not .bmp. It works for some images but for some images it doesn't. Re: GetBItmapBits() Abhishek Srivastava21-Nov-03 1:45 Abhishek Srivastava 21-Nov-03 1:45  Well the extension doe'snt matter, what i think is that u r saving it as DIB and even ur extension says it is a DIB .... try to read it as a DIB image may be it will solve ur issue!!
