i am gonna debug net framework source code in vs ,so i need that the source code version is the same with dll.now the source code is 4.6.1 ,i need 4.6.1 dll such as mscorlib.dll to be loaded not 4.7.2.
apologise for my poor english

My god . Now i just want to unistall .net 4.7.2 ,and I have not installed this version .net framework. But it is there ,the os is win10.Why can not I unstall?

now i have 4.7.1 source code,i want my app which targets .net 4.7.1 to run and load the same version assembly of 4.7.1 not 4.7.2 assembly

now i am looking for a way to uninstall version 4.7.2

Thanks a lot .I doubt that i have never install .net framework 4.7.2 but when running the exe , it will load the 4.7.2version dll .Why?
PS:I really hope my application well be running under v4.6 or lower.

Thank you . I wanted to debug .net 4.5.1 in vs. To keep source code and loaded dll match each other , I think load specified version dll is a good idea.
Now i have got the specified version dll ,the version is about file version . But I have no idea how to load it other than gac dll.

Yes,what I just want to know is the "dynamic menu mechanism".Thanks for your post.not long ago I did not know the phrase,now I know it is called "dynamic menu mechanism".

HFONT MyCreateFont( void )
{
CHOOSEFONT cf;
LOGFONT lf;
HFONT hfont;

// Initialize members of the CHOOSEFONT structure.

cf.lStructSize = sizeof(CHOOSEFONT);
cf.hwndOwner = (HWND)NULL;
cf.hDC = (HDC)NULL;
cf.lpLogFont = &lf;
cf.iPointSize = 0;
cf.Flags = CF_SCREENFONTS;
cf.rgbColors = RGB(0,0,0);
cf.lCustData = 0L;
cf.lpfnHook = (LPCFHOOKPROC)NULL;
cf.lpTemplateName = (LPWSTR)NULL;
cf.hInstance = (HINSTANCE) NULL;
cf.lpszStyle = (LPWSTR)NULL;
cf.nFontType = SCREEN_FONTTYPE;
cf.nSizeMin = 0;
cf.nSizeMax = 0;

// Display the CHOOSEFONT common-dialog box.

ChooseFont(&cf);//select a font form the list ChooseFontDialog of MS's CommDlg

// Create a logical font based on the user's
// selection and return a handle identifying
// that font.
//cf.lpLogFont->lfOutPrecision=OUT_TT_ONLY_PRECIS;
int err = GetLastError();
cf.lpLogFont->lfHeight=15;
cf.lpLogFont->lfPitchAndFamily=2;//set not seam width
hfont = CreateFontIndirect(cf.lpLogFont);
err = GetLastError();
if(err>0)
{
MessageBox(NULL,L"Failed",L"wrong",MB_OK);
}
return (hfont);
}

As I know ,as to every interrupt,a handler is here. So I want to find the handler of the interrupt that The timer can trigger,and I want to stop the context switch.If the context switch is over,I can trace a system call into the end.

Thank you very much!Now I am looking for the handler in windows os, some suggestion?

is the timer hardware not exist?"Timer interrupts are triggered in all cases"means that when the cpu is executing every instruction,the interrupt can happen?

thanks for your answer.i have read the intel manual and some other books about os,and i find that every time a context switch happens,a timer is triggered,and the handler begin handling the trap,the questions is where the handler is.i cannot find it as i find int3 trap handler.

thank you for your post ,I have seen the link you provided.

yes ,i really changed the mapping mode.Now I modify the mapping mode MM_TEXT,when I maxizime the window I find the rect.width is 1366 and the rect.height is 686. Thank you for your answer.

My goals is that I want to capture the point where the mouse is,whenever the mouse moves,the point changes and I want show the coordinates on the cursor.I know that,the cursor is really a bitmap,as a result I operate the bitmap and create and destroy the bitmap when the mouse moves. But I donot have a better idea.

thank you ,then How to use the function ExtCreateRgn,second element of the struct RGADATA ,char [1] that I do not understand what it means .

no

It is in single click .It will occur when I click on any special control.

I have told it again ,see it again please,thank you

thank you
