Hi All,
Last 20 days i spend my every morning to solved this exception but i can't get it.
Before i asked my question, let me inform you about my plateform of developement

1)Operating System:-Window 2003 server edition<br />
2)Microsoft visual studio 2003<br />
3)MFC Dialog based Application

______________________________________________________________________
Now,
I have one utility that take Three file from user as input.

1)BIL OF MATERIAL<br />
2)SALES PLAN<br />
3)MRP DETAILS

And on the basis of this file i genarate A Master file.

Concept working so far fine but as i allows user to enter 3 file.
so, I ask the user to select file from a CFileDialog.
There are 3 edit box and 3 browse button to do so.
Now,
When i select first file with file dailog say BIL_1.csv(*.CSV Excel file format)
File selected correctly.
But next time i click another Browse button another file dialog opens allows user to select next file but while selecting next file if my focus goes on BIL_1.csv(Previously selected file).
then instead of showing TOOLTIP text a UNHADLE EXCEPTION Came.
Unhadled Exception at 0x7c95a8ad in sapUtility.exe 0xC0000005:Access violation reading location 0x010f3850
SapUtility.exe is my project name.
A on click of break.

7C95A8A7 mov  eax,dword ptr[eax+1C4H]<br />
7C95A8d        mov  eax,dword ptr[eax]<br />

and value of eax is 17774672
__________________________________________________________________
NOTE:-
1)This happen when i select files from DESKTOP.there is lots of shortcuts.
2)This happen only with .csv files utill now.
3)This happen for Tool Tip text shown
4)I dont known this may be very confusing question.
5)May be microsoft BUG.
6)Please review my previous post.
MFC Error: CFileDailog Error of 0x7c95a8ad type exception[^]
________________________________________________________
[EDIT] FOR CODE:

void CSApUtiliy::OnBnClickedButton1()
{
  CFileDialog InputFile_BOM(TRUE,"CSV","*.CSV",OF_HIDEREADONLY|OFN_PATHMUSTEXIST,"csv Files(*.csv)|*.csv|All files(*.*)|*.*||",this);  //constructor
CEdit* Input_FileText=(CEdit*)GetDlgItem(ID_EDIT2);
if(InputFile_BOM.DoModel()==IDOK)
{
  CString PathName=InputFile_BOM.GetPathName();
  Input_FileText.SetWindowText(PathName);
}
}

And For Next Button

void CSApUtiliy::OnBnClickedButton2()
{
  CFileDialog InputFile_Sale(TRUE,"CSV","*.CSV",OF_HIDEREADONLY|OFN_PATHMUSTEXIST,"csv Files(*.csv)|*.csv|All files(*.*)|*.*||",this); //constructor
CEdit* Input_FileText=(CEdit*)GetDlgItem(ID_EDIT1);
if(InputFile_Sale.DoModel()==IDOK)
{
  CString PathName=InputFile_Sale.GetPathName();
  Input_FileText.SetWindowText(PathName);
}
}

Solution 4

could you try this?

void CSApUtiliy::OnBnClickedButton1()
{
	CFileDialog InputFile_BOM(TRUE,"CSV","*.CSV",OFN_HIDEREADONLY|OFN_PATHMUSTEXIST,"csv Files(*.csv)|*.csv|All files(*.*)|*.*||",this);  //constructor
	if(InputFile_BOM.DoModal()==IDOK)
	{
		CString PathName=InputFile_BOM.GetPathName();
		GetDlgItem( ID_EDIT2 )->SetWindowText(PathName);
	}
}

And For Next Button

void CSApUtiliy::OnBnClickedButton2()
{
	CFileDialog InputFile_Sale(TRUE,"CSV","*.CSV",OFN_HIDEREADONLY|OFN_PATHMUSTEXIST,"csv Files(*.csv)|*.csv|All files(*.*)|*.*||",this); //constructor
	if(InputFile_Sale.DoModal()==IDOK)
	{
		CString PathName=InputFile_Sale.GetPathName();
		GetDlgItem( ID_EDIT1 )->SetWindowText(PathName);
	}
}

Solution 2

this is an odd problem (I commonly use CFileDialog() and have never had this problem)... are you sure you're not trying to access these button simultaneously from different threads? ... another thing to try is to allocate and deallocate the heap manually (to see if forcing the deallocation of CFileDialog helps).

Call new CFileDialog() and delete CFileDialog() manually instead of allocating on the stack.

Another thing... why does the break show only assembly? ...if this is a CFileDialog on your dev machine, you should be able to see the code to see where this is breaking. Are you not seeing the problem in Debug or not using a Debugger?

I have been try this

Albert Holguin 25-May-11 1:19am

just updated...

[no name] 25-May-11 1:20am

Is there CFileDialog() constructor taking 0 argument.

Albert Holguin 25-May-11 1:23am

No, but there is one that takes only 1 argument, the initial argument that specifies the type of CFileDialog... also, try allocating the CString outside of the if() statement, to see if its maybe being deallocated before it gets a chance to be posted

[no name] 25-May-11 1:22am

UPDATED:
With debug too i goes on Assembly

Albert Holguin 25-May-11 1:26am

typically when it goes to assembly it means that there's no source code for that piece of code... which if you're using MFC, the source should be there...

Albert Holguin 25-May-11 1:28am

Also note that the call should be DoModal() not DoModel(), I don't know if that's just a typo

Albert Holguin 25-May-11 1:30am

Also just noticed that this Input_FileText.SetWindowText(PathName); should really be this Input_FileText->SetWindowText(PathName); since its a pointer

[no name] 25-May-11 1:39am

What do mean by out side the if()

Albert Holguin 25-May-11 1:42am

outside of the brackets of the if() statement, since that CString is generated within the brackets of that if() statement, it will only persist on the stack until it goes out of scope, which is at the end bracket of the if() statement... if for example, SetWindowText() happend to be asynchronous, the variable may be deallocated by the time that call uses the variable.

Albert Holguin 2-Jun-11 0:22am

First make sure of those things I pointed out above (make sure DoModal() is called correctly) and make sure you're using '->' operator instead of '.' in the SetWindowText() calls.

do you have Visual studio 2003

Albert Holguin 25-May-11 1:24am

I've programmed in studio 6, 2003, 2005, and 2008... but I only have 2008 on this machine

[no name] 25-May-11 1:37am

All you mention is just typo becouse i cant access my server code to stand allone NET machine

[no name] 25-May-11 1:42am

This links provide CFileDialog With 7 parameter as constructor argument

Albert Holguin 25-May-11 1:47am

THEY'RE ALL DEFAULTED EXCEPT FOR ONE! ...this sort of proves that you don't know what you're doing at an elementary level... Sorry but its late, I'm off to sleep.

[no name] 25-May-11 1:49am

Its OK Goog night surly next morning we have chat.
And Placing CString outSide if()
not working

[no name] 25-May-11 1:49am

What is
THEY'RE ALL DEFAULTED EXCEPT FOR ONE!

Albert Holguin 25-May-11 1:50am

I give up

[no name] 25-May-11 1:50am

Dont say that please!

Solution 3

Try making the calls like this:

void CSApUtiliy::OnBnClickedButton1()
{
  CString PathName;
  CFileDialog InputFile_BOM(TRUE);  //constructor

  CEdit* Input_FileText=(CEdit*)GetDlgItem(ID_EDIT);
  
  if(InputFile_BOM.DoModal()==IDOK)
  {
    PathName=InputFile_BOM.GetPathName();
    Input_FileText->SetWindowText(PathName);
  }
}

if that works, then add arguments into the CFileDialog until you get it to do what you want.

What is difference And CFileDialog not gets one parameter let me remind you

Albert Holguin 2-Jun-11 0:37am

see, you need to go back and learn a bit more C++...

Albert Holguin 2-Jun-11 0:38am

...and don't downvote me unless you want me to return the favor...
