either you need to have a protocol implementation in your Clien-Server communication or you have to make sure that you send all the buffer at one time. If you are choosing a protocol means you first send a message to the server that am going to send a image buffer with size/length X and at the server store this and use this value for the next receive command.
If you are going to use whole buffer at one time, just use that buffer as such to create re-create your image. having a protocol is the best choice. if you google you can find many protocols choose the simplest one that suits your requirement.
Hello everybody i have a small question , not big enough for the quick answers . I am working on a MFC project a little bit old. And i had to add a header to the print result. My problem was with the font Size. After some tries i found the really useful Article about Printing trics. The problem was when i used
Printing was ok but the PrintPreview wasnt. The font size was still small and i know why the GetDeviceCaps was returning the dpi of the monitor. This was understandable . After some digging in the code i found that for the rest printed text the font size was calculated a little bit different. For the font Height was taken the absolute value of the height multiplied by the zoom and all divided by some constant. My question is is there some practice about that kind of calculation . To be honest i don't think its a good idea to use it. I don't believe that all printers will print the same thing. But the PrintPreview and the Print result are pretty much the same.
What do you think ?

We have developed a COM DLL 64 bit on Windows Server 2008 R2 - 64 bit and this dll is successfully register when visual studio 2010 is installed on the machine but when on a fresh machine its unable to register with following error:
module xxxx.dll failed toload
make sure the binaryis stored at the specified path or debug it tocheckfor prob with the binaryor dependent dll files
After a lot of investigation, we found that if Microsoft C++ runtime 2010 10.0.3019 is installed, then only dll will be registered. Can anyone provide the required list of dependecy. Thanks in advance.
