Good Morning,
I have 99 CEdit I want to do a loop and pick
the text of there 99 text and concatenate them in
a Cstring here an exemlpe
for (i=0;i<=99;i++)
allString=allString + the content of CEdit[i].the function to extract the text;
I found an exemple on VB
For i = 0 To 99
HolayString = HolayString & txtHol(i).CtlText
Next i
how i do it in VC++
thanks a lot Sleepy | :zzz:

Supposing you have created a dialog based application with 99 edit box ( Use Microsoft App wizard for creating Dialog based App)

Then suppose there is a button on the dialog and on clicking you need the 99 text. Then handle the BN_CLICKED event of the button

CMYDlg::OnButton1()
{
CString MyStr;
For( i = 0; i<=99; i++ )
{
MyStr += EditArray[i].GetWindowText(); //Supposing the CEdit EditAray[99] is declared and created.
}
AfxMessageBox( MyStr );

}

few remarks :

1) you dont construct the EditArray
2) you don't initialize MyStr
3) it should be for, not For
4) GetWindowText() don't work that way

otherwise, the concept is good Cool | :cool:

you can do 3 ways :

(1) common way. you have a variable for each edit, and access it with m_edit.GetWindowText(strContent). you do that for each and then you Create a CString which is a concatenation of all of them... quite hard to do !

(2) brute way. you ensure that ever editBoxes IDs are following each others (like IDC_EDIT1 == 1001, IDC_EDIT2 == 1002, etc...). then, you can make a for loop from IDC_EDIT1 to IDC_EDIT99, read their content and contatenate like in (1).

(3) more Subtle solution. you create a list (std::vector will do) with references to the 99 editboxes. the only matter is that they are puched in the correct order in the list so that you read them good. then you do this :

std::vector<UINT> vec;
vec.push_back(IDC_EDIT1);
vec.push_back(IDC_EDIT2);
//construct the vector to the end, once. OnInitDialog() is a good place for that...
 
CString strAll = _T(""), strItem = _T("");
std::vector<UINT>::iterator iter;
for (iter = vec.begin(); iter != vec.end(); iter++) {
    GetDlgItem(*iter)->GetWindowText(strItem);
    strAll += strItem;
}

The IDC_EDIT as value or as Control

IDC_EDITnn are the edit IDs, so UINT

but you could also make a vector of CEdit directly (of a vector of pointers to CEdit to reduce the memory allocated). you would then access datas by :

CString strAll = _T(""), strItem = _T("");
std::vector<CEdit*>::iterator iter;
for (iter = vec.begin(); iter != vec.end(); iter++) {
    (*iter)->GetWindowText(strItem);
    strAll += strItem;
}

Hi all,

We are developing wildcard script maps for WSS&SPS(windows sharepoint). During this process we
have faced a problem! When we have installed this wildcard script map(ISAPI
extension) to a virtual server, we cant visit any site - error 404, after
examining logs, we find out that WSS just couldn't connect to DB. As i
understand, this ISAPI extensions is called before all other extensions and
filters, and just doesn't allow to launch other.
Could anyone assist me in this problem please?

thanx in advance

Setting the Cursor

I did search and try this section of code; but the cursor did not change?

BeginWaitCursor(); // display the hourglass cursor
// do some lengthy processing
EndWaitCursor(); // remove the hourglass cursor

This was for a Visual Studio 2005 MFC C++ Dialog application.

I just want an hourglass for a few minutes while some processing is taken place.

Many thanks,

Andy.

I think it should work can you paste your code here ?

Also try using LoadCursor(...)

// Set hourglass cursor:<br />
BeginWaitCursor();<br />
	while (!g_pRecordset->GetadoEOF() /* && g_nLineCounter < 1000 */)<br />
	{<br />
		// Obtain the MessageDisplayName<br />
		g_TheValue = g_pRecordset->Fields->GetItem ("MessageDisplayName")->Value;<br />
		g_szMessageDisplayName.Format("%s", (char *)_bstr_t(g_TheValue));<br />
		j++;<br />
		ProcessMessages();<br />
	} <br />
	EndWaitCursor();<br />
	output.AppendFile(g_szFileName, m_lineData);

Nothing happens with the cursor, I use ProcessMessages() to pump the message queue so that I can update a listView that is being populated.

Any suggestions?

Is there any reason not going for CWaitCursor ?
You code would be modified like this,

// Set hourglass cursor:
CWaitCursor wait;
while (!g_pRecordset->GetadoEOF() /* && g_nLineCounter < 1000 */)
{
// Obtain the MessageDisplayName
g_TheValue = g_pRecordset->Fields->GetItem ("MessageDisplayName")->Value;
g_szMessageDisplayName.Format("%s", (char *)_bstr_t(g_TheValue));
j++;
ProcessMessages();
} 
output.AppendFile(g_szFileName, m_lineData);

You only need to construct its object.

Although this code may well work, it's also possible that the ProcessMessages() call could cause the cursor to return to the standard arrow.

If that is happening, add a
wait.restore();
after the ProcessMessages() call.

Hope that helps.

I wanted to add this in my post,too. Which is mentioned in MSDN standard example.
But avoided, for sake of confusion.

Yes, you can always restore wait cursor with Restore call.

SetCursor(...);
You can also change the cursor with your methodology. Did you check whether the lines of code that lie with in the
BeginWaitCursor();
// Some code here.. Take some time here
EndWaitCursor ();

Block are consuming that much of time for you to see the effect on your screen.

Somethings seem HARD to do, until we know how to do them.
