Whats wrong with the following, actually my VC++ application is not calling ActiveX method it says "Object Reference Error", i can able to compile successfully.
brFileContent->Read (abData,0,2); //brFileContent is Binary Reader
Byte *pbManagedData = &(abData[0]); // Get starting point of Array (I can able to see Data and address here
axSimpleAdditionAtx1 ->FinalBy (pbManagedData); // Calling Activex
Method signature in ActiveX which is not getting called..
void VRMControl::SendBy(BYTE* ByteValue, LONG Length)
{
}

Shouldn't it be as ... below (the dot) ?
axSimpleAdditionAtx1.FinalBy (pbManagedData); // Calling Activex

No it should be pointer i can able to call some other methodes, this alone is giving thie error seems there is some signature or data mismatching that i am not able to find out please help me out.

Can you give the prototype of FinalBy of ActiveX control your trying to use?
Maxwell Chen

This is the prototype which i am using in ActiveX
void VRMControl::FinalBy(BYTE* FinalStr)
{
AfxMessageBox ("Called..");
}
Even the message "Called.." is not displayed before that itself it throws error.

Then it should be other reason about the initialization of that ActiveX instead of invoking the method FinalBy(...).

Some alternatives:
strcpy(str, (LPCTSTR) FName);
strcpy(str, FName.GetBuffer(0));
OR:
char * pStr = (LPCTSTR) FName;

See the following code
strcpy(str,FName.GetBuffer(0));
FName.ReleaseBuffer();
Hope this helps you

Hi Laxman,
Do u remember yesterday i had asked u for changing the file path
C:\folder\folder\file.ext
to
c:/folder/folder/file.ext
now i have written a small program in which will change the input and get the output as
c:/folder/folder/file.ext
now i am facing one more problem file is not opening
ShellExecute(NULL, "open", str,NULL, NULL, SW_SHOWNORMAL)
is this the correct way to open the file is the code correct...
str is of char array
char str[100];
|
|
|
|

Can you show me the code how you changed the string path?
May be there was any bug i think code is correct.

Hi Laxman,
below code changes c:\folder\folder\file1.txt
to
c:/folder/folder/file1.txt
void CSearchDlg::OnDblclkSout()
{
// TODO: Add your control notification handler code here
// Code to open the selected file.
int d;
d=m_SOUT.GetCurSel();
CString FName;
m_SOUT.GetText(d,FName);
char str[100];
int i,l,k,j,m;
strcpy(str, FName);
for (i=0;str[i]!='\0';i++)
{
if (str[i]=='\\')
{
l=i; k=0;
char str1[100];
if (str[l+1]=='\0')
{
str[l]='/';
}
else
{
for (j=l+1;str[j]!='\0';j++)
{
str1[k]=str[j];
k++;
}
str1[k]='\0';
str[l]='/';
for (m=0;str1[m]!='\0';m++)
{
str[++l]=str1[m];
}
}
str[++l]='\0';
i=i++;
}
}
m_ctrlEDIT.SetWindowText(str);
ShellExecute(NULL, "open", str ,NULL, NULL, SW_SHOWNORMAL);
}

Try the following code as its tested and works fine.
CString str;
m_SOUT.GetText(m_SOUT.GetCurSel(),str);
ShellExecute(m_hWnd,NULL,str, NULL, NULL, SW_SHOWNORMAL);
m_ctrlEDIT.SetWindowText(str);
Hope this solve your problem.

How this is possible?
Your path in list box should be either
C:/Box01/00000304/00000034.txt
or
C:\Box01\00000304\00000034.txt
i think you are not inserting the data into list box correctly..
have you?

Hi,
In the list box items are like
C:\Box01/00000304/00000034.txt
C:\Box01/00000304/00000035.txt
C:\Box01/00000304/00000036.txt
but after the function i get the value in the str as
C:/Box01/00000304/00000034.txt
since the path is correct with file name it should open right ??

Can you post the block for insertion of the data into list box ?
and Do you want to open only .txt files?

Hi,
code for inseting file names to list box & i have open only txt files only.
void CSearchDlg :: disp ()
{
int i = 0;
while (strlen (shWord[i].file_name) > 1)
{
m_SOUT.AddString(shWord[i].file_name);
int k = 0;
TCHAR buff[100];
strcpy(buff,"\0");
while (shWord[i].w_offset[k] != -1)
{
TCHAR buffer[50];
int f=shWord[i].w_offset[k];
_itoa(f,buffer,10);
strcat(buff,buffer);
strcat(buff,",");
k++;
}
buff[strlen(buff)-1]='\0';
m_SOUT.AddString(buff);
i++;
}
}

Hi Laxman,
I got the solution, the problem was some junk character was getting added to the file name,so it was not able to open file,i just altered the file name removed the last junk character str[i-1]='\0';now the file open properly...
Since its in the list box user keep on cliking on items and open any number of files but i want only file to be open at a time..
when the user clicks on the item i want the open file to closed(txt files) and slected file to opened is there any way to close and then open a file ??

You have to trace the running processes and get the Handle of the NOTEPAD.exe which is the default application of the .txt files and terminate that process before executing the ShellExecute.

use
CString FName123;
char str123[100];
FName123="test";
wsprintf(str123,"%s",FName123);
--------------------------
or
str123[0]='\0';
strcat(str123,FName123);
