Re: Deleting Start-Menu Folder

30-Apr-04 8:15

I'm curious why you'd want to remove the Start Menu folder. Trying it yields a "Start Menu is a Windows system folder and is required for Windows to run properly. It cannot be deleted." message.

Bad wording on my part. A menu ON the start menu. We have an application that re-installed itself somewhere different during an update leaving people with a bad shortcut on the start menu.

I've worked out a program to delete all of the .lnk files pointing to the old directory, but was having trouble deleting the directory.

Since my original post I've realized that the problem was that I was trying to remove the directory while a FindFile was still pending on the directory. Once I moved the delete routine to another part of the program all worked fine.

localization with satellite dll's

How can I change the language at run-time. I use resource-only dll's for the different languages and set it in the MFC method CWinApp::InitInstance with AfxSetResourceHandle before the MainFrame is loaded. How can I do this, when the MainFrame is already loaded. What do I have to do besides the AfxSetResourceHandle, that even the Menu and all the dialogs are now in the new language? Thanks for any help.

Hi In one column of List Control i want to show the image but not the values, but with my code(pasted below) it is showing both the image and values. Can any body help me how can i achieve this.But i need to associate the values also because i am doing sorting also on that column

//Set up Record Status
Holder = pRecordSet->GetCollect("RecordStatus");
status = Holder.iVal;
temp.Format("%d",status);
m_RecordList->SetItemText(iNew,5,temp);

// setup record status
lvI.mask=LVIF_IMAGE ;
lvI.iItem= iNew;
lvI.iSubItem=5;

if(status == eCIT_STATUS_COMPLETE)
lvI.iImage = 1;
else if(status == eCIT_STATUS_VOID)
lvI.iImage = 3;
else
lvI.iImage = 0;

m_RecordList->SetItem(&lvI);

Thanks

Isn't the call to SetItemText() what's showing the value?

SetItemText() is showing the value but how can i associate a value with the image so that i can sort by clicking on header. But it is showing both values and Image.

Thanks

Call SetItemData().

Hey this is the situation now but it is not sorting when i click on the header column.

//Set up Record Status
Holder = pRecordSet->GetCollect("RecordStatus");
status = Holder.iVal;
m_RecordList->SetItemData(iNew,status);

// setup record status
lvI.mask=LVIF_IMAGE ;
lvI.iItem= iNew;
lvI.iSubItem=5;

if(status == eCIT_STATUS_COMPLETE)
lvI.iImage = 1;
else if(status == eCIT_STATUS_VOID)
lvI.iImage = 3;
else
lvI.iImage = 0;

m_RecordList->SetItem(&lvI);

Any Suggestion
Thanks

This is the code that populates the list control. I wanted to see the code that handles the clicking of the column heading, and the sorting-compare routine.

How can i pass MFC pointers to non MFC DLL's?

30-Apr-04 10:53

In the ListViewCompProc() routine, don't call FindItem() or GetItemText(). Use the lp1 and lp2 parameters instead. See MSDN article Q250614.

Console Application

Hi.

I am using ::CreateProcess(...) to start a new console process. When the process finishes the job, the console window closes, avoiding the user to see messages or process results.

Is there any way to keep the window opened after process end?

Thanks.

A hack might be to create a batch file that launches the process, and then has a PAUSE statement, so that it won't finish until the user presses a key.

Or, if you own the concole process, you could change its code to ask for a keypress before closing. (Perhaps make it a command-line parameter.)

There might be a way to keep the console window open until you, say, click its close button, look at the CreateProcess parameters and see if there is anything. But I don't know for sure.

Sometimes I feel like I'm a USB printer in a parallel universe.

I have created a MFC ActiveX control to interface with a finger print scanner. For that
i had to create a DLL (MFC Extension) which was used to interface between the MFC ActiveX
and the Win32 based API supplied by the scanner vendor. I had to do this since i wanted to
do some drawing on MFC created objects. I was forced to create the MFC Extension DLL coz
MFC pointers are only allowed to be passed across MFC Extension DLL's and not to ordinary
DLL's(that is what i know). The DLL that i created should also work as an interface between
any program who want to manipulate the scanner from different languages (like Java and Visual
Basic). I have two questions here
1) How can i create the DLL not as MFC Extension DLL but as ordinary DLL and still
access MFC pointers?
2) I am not able to load this DLL and call its functions in VB.

Any kind of help is appretiated.

Thank you in advance.

Use a window handle (HWND), not a CWnd pointer.
