Hey...
I'm trying to make a simple little program that takes a string, searches for that string in a different string, and once that string is found, replace it with a different string. I want it to do this to the end of the string.
I'm kinda stuck right now, cause I don't know how to use the CString::Insert() and Find() functions right. I had a function that Replace()'d everything, but the problem was that I was trying to replace "\r\n" with "<br>\r\n", so it kept looping around and inserting till I had something that looked like: "Hello World<br><br><br><br><br><br><br><br><br><br>\r\n".
Also, in the replace function I'm using it uses lstrlen() functions, and I'm not *exactly* sure what those do.
If someone could point me to an article where it talks about things like this, or gave me some advice in a reply, I'd be very thankful.
Thanks, Emearg
The function I'm using:
CString CMFC2Dlg::Replace(LPCTSTR instr, LPCTSTR oldstr, LPCTSTR newstr)
{
CString output(instr);
CString input_lower(instr);
CString oldone_lower(oldstr);
input_lower.MakeLower();
oldone_lower.MakeLower();
int pos=0;
while ( (pos=input_lower.Find(oldone_lower,pos))!=-1 )
{
input_lower.Delete( pos, lstrlen(oldstr) );
input_lower.Insert( pos, newstr );
output.Delete( pos, lstrlen(oldstr) );
output.Insert( pos, newstr );
}
return output;
}
Called by:
LogConvert = Replace(LogString, "\r\n", "<br>\r\n");

Since you make a call to Insert when you replace the the search string with newstr you need to move pos past the newly inserted string. So, try this:
while ( (pos=input_lower.Find(oldone_lower,pos))!=-1 )
{
input_lower.Delete( pos, lstrlen(oldstr) );
input_lower.Insert( pos, newstr );
output.Delete( pos, lstrlen(oldstr) );
output.Insert( pos, newstr );
pos += lstrlen(newstr)
}
lstrlen returns the length of the argument you pass it (i.e. the number of characters contained in the string.

I'm making an app where i need to search thru all the files in a folder, and also all the files in it's subfolder and it's subfolder's subfolders etc. I'm having some problems developing an algorithm for this. can anyone shoot me in the right direction? I don't need a complete set of code, just some advice on how to handle it. I know how to add all the files from a folder when i have the ITEMIDLIST of it.
Thanks

try looking in the Files and Folders section of this site. there are probably half a dozen classes that will do this (including mine).

func FindDirs(array DirArray string curDir)
file = FindFirstFile(curDir)
if (file is dir)
add file to DirArray
FindDirs(DirArray, file)
end if
file = FindNextFile(curDir)
while (file is ok)
if (file is dir)
add file to DirArray
FindDirs(DirArray, file)
end if
file = FindNextFile(curDir)
end while

You have to write recursive function.

but here it is (I hope it works). You will get files from folder 'pstr' in 'files' array.
void RecurseAdd(CStringArray & files,LPCTSTR pstr)
{
CFileFind finder;
files.RemoveAll();
// build a string with wildcards
CString strWildcard(pstr);
strWildcard += _T("\\*.*");
// start working for files
BOOL bWorking = finder.FindFile(strWildcard);
while (bWorking) {
bWorking = finder.FindNextFile();
// skip '.' and '..' files
if (finder.IsDots())
continue;
// if it's a directory, recursively search it
if (finder.IsDirectory()) {
RecurseAdd(files,finder.GetFilePath());
} else {
files.Add(finder.GetFilePath());
}
}
finder.Close();
}

If i have a function, that with the id of a folder, it goes through all of the elements of the folder, if it is a file it adds it to a list, and if it is a folder it calls itself. wouldn't that work?
BTW, thanks all!

Is there anyway to set the text color for inidividual ListView subitem? You can change the text color of the whole listview using SetTextColor method of listview, but it seems that it sets the whole list...is there anyway to set the color for individual items?
thanks

I'm writing an MFC VS 6.0 program that passes text variables to BRIO a reporting tool.
I know how to return a variable with a C++ program but how do you call an external program in MFC??
MSDN is as much help as it usually is.
Thanks

I am working on a C++ app to populate acrobat fields. I have figured it out in VB and that code could be posted if needed. What I need is how to use the AForm32.api plug-in in C++. Are there headers? Is there a way to #import. I have played with #import but don't seem to have exposure to the objects. Thanks for any guidance.

Hi:
I have written the following code for sorting the column on a lift mouse click:
void CMyListCtrl::OnColumnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// Get the current mouse location and convert it to client coordinates
DWORD dwPos = GetMessagePos();
CPoint cPt(LOWORD(dwPos), HIWORD(dwPos));
ScreenToClient(&cPt);
// Get the number of columns
int nColCount = ((CHeaderCtrl *)GetDlgItem(0))->GetItemCount();
// Determine what column was clicked
int nLeftBound = 0;
for (int nColIndex = 0; nColIndex < nColCount; nColIndex++) {
int nColWidth = GetColumnWidth(nColIndex);
if ( cPt.x >= nLeftBound && cPt.x <= (nLeftBound + nColWidth) ) {
// Call the sorting function
m_bColSortOrder[nColIndex] = !m_bColSortOrder[nColIndex];
if (m_nColDataType[nColIndex] == 1) {
SortNumericItems(nColIndex, m_bColSortOrder[nColIndex], 0, GetItemCount() - 1);
} else {
SortTextItems(nColIndex, m_bColSortOrder[nColIndex], 0, GetItemCount() - 1);
}
}
nLeftBound += nColWidth;
}
*pResult = 0;
}
That works great until I scroll horizontally within the list control. As columns get shifted, the click doesn't point to the right column anymore..
Any thoughts?
Thank you

Hi,
All the code you have written to get the column is
not required. You get the column fromt he NM_LISTVIEW struct itself.
Look at the foll. code snippet.
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
*pResult = 0;
int nColumn = pNMListView->iSubItem ;

I am getting a debug assertion that I havn't ever seen before, and I cant figure it out.
If anybody has any ideas pls let me know.
Thanks
Here is the constructor dec:
CModemInterface(CStringArray* out, CWnd* pParent = NULL);
And here is where I call the dialog:
CStringArray* testFiles = new CStringArray();
for(int i = 0; i < 5; i++)
{
CString strTemp;
strTemp.Format("Test%i.txt", (i + 1));
testFiles->Add(strTemp);
}
CModemInterface dlg(testFiles, this);
if(dlg.DoModal() == IDOK) //crash here, traced into CDialog::DoModal
delete testFiles;
return;
|
|
|
|
|
What kind of assertion do you get? Does it crash in OnInitDialog?
Best regards,
Alexandru Savescu
|
|
|
|
|
In dlgcore.cpp, function CDialog::DoModal():
// can be constructed with a resource template or InitModalIndirect
ASSERT(m_lpszTemplateName != NULL || m_hDialogTemplate != NULL ||
m_lpDialogTemplate != NULL); //Fails here
this is the first line of the function.
any thoughts??
thanks

When you wrote the CModemInterface class constructor, did you remember to call the default CDialog constructor, passing along the dialog template Id?
CModemInterface::CModemInterface (CStringArray *s, CWnd *pWnd)
: CDialog (CModemInterface::IDD, pWnd)
{
}

Does anyone know of a printf() replacement that will print numbers with commas? For example:
printf("Number is %D\n", num);
Number is 198,456
I need all the normal functionality of printf, but with the comma'd decimal numbers. I realize there are a lot of international concerns with commas, but those aren't an issue for my needs.

i don't think there is such an option - you'll have to do this one by-hand
