Convert an EXE file to a DLL file in VC

Convert an EXE file to a DLL file in VC

Speaking of the method here, we have to say that VC is the function of each file generated in it:

. DSP engineering file, in text format, cannot be lost or damaged
When the. DSW workspace file is lost or damaged, you can click. DSP file to open the project and the. DSW file is automatically rebuilt.
. CLW classwizard information file, INI format, classwizard can be deleted and rebuilt if a problem occurs
. Map image information file. If you do not know the function export sequence when compiling the dll Write. Def file, you can select it on the prject/settings/link page.
"Generate mapfile", re-build, use notepad or other similar programs to open the generated. map file, which shows the function export table
. I enter Cl *** in the command line environment ***. CPP/P (note that the parameter P is case sensitive), which is generated in the program folder. I file, open it with notepad or other similar programs, you can see. results of the CPP file after preprocessing. NCB does not compile the browsing file. When the function is automatically completed (the list of member variables is automatically displayed), you can delete it and re-build it automatically.
Others:
. APS resource auxiliary file, in binary format
. Opt development environment parameters (such as tools

Location) File
. PLG compilation information (such as error and warning information) file, in HTML Format
. PCH pre-compiled files can speed up compilation, but the file size is very large.
. PDB Records Program-related data and debugging information
. Exp DLL information file, generated only when the DLL is compiled
. BSC is used to browse project information.
"Generate browse info file" is removed from the prject/settings/link page ",
Prohibit generation of. bsc files to accelerate compilation. However, if source browser is used
This file is required.
The other files that are useful to us today are the *. DSP file, which stores some configuration information of the project. Therefore, to achieve our goal today, we need to change the configuration information in * .dsp. in this way, we can convert a. EXE file into the DLL file we need.
Now let's get started:
1> create three VC projects. The names are: demodll(.exe generated by the dialogclass, which is used to convert it to the DLL file we want) DLL (default mfc dll) and calldall (the dialog class is used to call the DLL file we convert)
2> open the demodll. dsp dll. DSP file respectively.

Well, I have already marked the differences between the two files. Of course, we only need to modify the differences here. To implement our functions today, we only need to modify the ones marked above.
This is the modified demodll. DSP.

Okay, that's all. The above is the modified demodll. the contents of the DSP file need to be modified in 13 places. In fact, there is nothing to do with it. As long as you can see it clearly, it will be OK.
Now, we can convert the file. Let's call it:
Calldll.exe:
Void ccalldlldlg: onok ()
{
// Todo: add extra validation here
Hinstance;
Hinstance =: loadlibrary (".. // demodll. dll ");
If (! Hinstance)
{
MessageBox ("loadlibrary is falied! ");
Return;
}
Freelibrary (hinstance );
Cdialog: onok ();
}
I will not post the specific execution results here. You can see the execution results after you execute them yourself.
