dear all,I have a question,when I write files,like pdf,i want to popup a dialog with animation to show
that the writing operation is working.
I don't know how to do with that ,it may need a avi file ,use CAnimateCtrl,is it need multithread,please
help me.this is my code
// TODO: Add your command handler code here
ExPro = new CExportPro();
CFileDialog dlg(FALSE,TEXT("txt"),NULL,OFN_HIDEREADONLY|OFN_FILEMUSTEXIST|OFN_PATHMUSTEXIST|OFN_OVERWRITEPROMPT,_T("TXT (*.txt) |*.txt|"));
filePath = dlg.GetPathName();
m_filepathname = dlg.GetPathName();
if ( !filePath.IsEmpty())
CString str(TEXT("hello this is the test for write process"));
Perform all your file writing operations in a background thread, and compute and post messages on the operation progress from the worker thread to your main window. Your main window procedure should handle this message and display the progress accordingly.
Thanks,but I use CAnimateCtrl,this is a control,I initial it in dialog CExportPro::OnInitDialog(),I think
when modalless diaolog appear,the control should be appear ,but the fact is that when writing it appear modalless diaolog without CAnimateCtrl,and after writing,the CAnimateCtrl show,why,it maybe the thread
hang_up.how to do with it.
You cannot run Windows unmanaged programs on Linux. You can do the base development as long as your code is POSIX compliant, but you would be better getting access to a Linux system and using the Linux development tools.
One of these days I'm going to think of a really clever signature.
People, I met a rather strange situation. I deleted a small memory block and after it was not able to allocate another one. Operator "new" presented me with "out of memory" exception. But without previous call of "delete" "new" gave me what I asked it for (I'm talking about small blocks, something like 10KB). At that very time VirtualAlloc() successfully allocated required memory. How could it be?
Yeah, of course I thought about it, but was not able to detect where this sorrowful situation took place. Usually when I wrote something outside of allocated memory block, I got a message when "delete" operator was called, but not now. I tried to check surrounding memory, allocated larger then I needed block, wrote canary words before and after memory that I used and found that these canary words remained intact.
Situation is worse, than I expected. Some malicious code is running at my comp. For the beginning, my Visual Studio 2005 refused to create the Project Property window and gave me something like "failed to create Net. Framework property grid". Trying to understand, why my prog refuses to open files, which it was able to open some days ago I found that in my process's address space was downloaded libraries like urlmon.dll, netapi.dll, crypt32.dll and modemInst.dll (!!!). People, I write prog which is intended to work with aerial images and I have no intention to counteract with the Net. The most interesting is the last library- it was taken not from system32 catalog, but from folder where HSPA USB Modem was placed.
Is there any tool to findout memory leaks in an ActiveX (build using C++/MFC). This ActiveX is loaded through a webpage in IE. I want to find out leaks at run time on certain operation in the ActiveX specially during unload. I tried bound checker but there is no such option to attach IE with it.
There is no reasonable scenario in which a QA department could be expected to verify those and no way that Operations/Support could be expected to put thousands into production at the same time.
Thus a planned rollout involving small sets is required. And small sets can be upgraded manually.
Even if everything went smoothly with say the first 100 one would still want to have a grace period between production and the next batch to insure that some serious problem didn't develop. Attempting to rollback tens versus thousands of apps is obviously very different.
It might be part of a bigger process to upgrade their code-base to a newer compiler/system; maybe a year long process (not uncommon for large systems).
Maybe they have a unit test system in place to validate all their code and system tests to validate the outputs.
I think thinking about a way to automatize converting their project files is good thinking; I would not want to have to double click on 1000s of dsw/dsp in VS2010 and manually upgrade the project files.
