All,
I am loading a string into a CEdit box and want the cursor at the EOL so user can immediately add text.
When I try to use CEdit member function to do this, compiler complains that my variable is a CString type - which of course it is.
Have studied "Using the CEdit control" By Wolfram Steinke but can not duplicate how he assigned 2 variables (a CString type AND a CEdit type) to the same edit box.
Any help would be much appreciated!

Create your member variable of CEdit type - MFC Wizard "Add Member Variable" dialog has "Variable Type" combo for this. You can also keep two variables of different types for one control.

Thanks Alex,
I've got that working (thank-you!), but there still seems to be a "trick" I am missing.
If I write a simple test program that writes to and reads from an edit control, everything seems to work fine.
My "control CEdit" variable is: mc_editkey
=== for example, the following works fine:
mc_editkey.SetWindowText("some stuff");
int len = strlen("some stuff");
mc_editkey.SetSel(len,len,FALSE); //need to put cursor at end
mc_editkey.SetFocus();
UpdateData(FALSE);
===this seems to work fine also;
UpdateData(TRUE);
mc_editkey.GetWindowText(buf, bufmx);
But at other times, the SetWindowText() function does not seem to work and also any attempt to force the cursor to the end of the line also does not work.
Are there any tricks to getting the control to "pay attantion to me"?
Is it possible to issue UpdateData(FALSE) at the wrong time or too many times?
I think there is something(s) fundamental I am missing. For example when the Diaolog Box pops up I want the focus to be in the edit box, i.e. I want the cursor to be there. So in the OnInit function I issue:
mc_editkey.SetFocus();
UpdateData(FALSE);
But it never works.
Much thanks in advance,
Robert

UpdateData doesn't matter for variables of type Control such as CEdit, CComboBox etc., it works for variables of Value type such as CString, int... To set focus on dialog control use CDialog::GotoDlgCtrl. Don't forget also to set Tab Order in dialog resource editor (Layout menu).

Thank-you again Alex,
I pretty much have it working.
In the syntax for CDialog::GotoDlgCtrl it asks for CWnd* pWndCtrl as a function parameter.
I confess that I'm not sure which variable to use.
Best to you, Thanks again,
Robert

Write GoToDlgCtrl(GetDlgItem(nID)) or use variable of control type (CEdit etc.): GoToDlgCtrl(&m_edit_box).

Alex ... again... thanks,

Hi Robert!
I have encountered the same problem, specifically when subclassing the control.
See this thread.
SetWindowText() does not work well for me,
so I resorted to using ReplaceSel() instead.
To move the caret to the end, try:
mc_editkey.SetSel(0, -1);
mc_editkey.SetSel(-1, -1);
Now, use ReplaceSel to append text:
ReplaceSel(buf);
In your case, I think it might be enough with ReplaceSel(), since it should move the caret to the end.
There is no need to use UpdateData(), it will work anyway.
Do you return FALSE from OnInitDialog()? You must do that when setting the focus on a control. See CDialog::OnInitDialog in MSDN.
Cheers,
/Fredrik

Hi
How can i get the time From the pc clock?
|
|
|
|
|
CString strTime = COleDateTime::GetCurrentTime().Format("%I:%M:%S %p, %m/%d/%y");
CString strTime = COleDateTime::GetCurrentTime().Format(_T("%I:%M:%S %p, %m/%d/%y"));
The format adjusts how it ends up looking I don't know the specifics but it should be in VC++'s help.

Hi everyone. Does anyone know how, or where I can go to find out how to detect the current version of MDAC is installed on a user's computer? I want to make sure the user cannot run a program I wrote without having the minimum required version of MDAC installed first.
|
|
|
|
|
use this code on ::InitInstance to check if MDAC is installed
CLSID clsid;
HRESULT hr = AfxGetClassIDFromString("Datalinks", &clsid);
if(!SUCCEEDED(hr))
{
AfxMessageBox("You need to install MDAC v2.1 orhigher"); return FALSE;
}
the version number is held in the registry, I think
HKEY_CLASSES_ROOT\MDACVer.Version with a subkey CurVer with the value like MDACVer.Version.2.60.

I just want to know what kind of APIs and stuff I would need to write a winzip like program.

I suggest you get a copy of the zlib library, which is free, very good, massively used and has rather good support at its website.

Hi,
I want to print a newline when I am pressing the enter key.
How is it possible in the case of WM_CHAR message?
SSN

Where do you want to print it ? If in an edit control, make sure it is set be be multiline, and it will do it by itself when you hit return.

In OnEraseBackground, get the client rect and fill it with the color you want using FillSolidRect.

I am missing something when using CDaoRecordset in an AppWizard generated application.
The database is intended to store the peoples name, and email address among other things. The program will display the records one at a time and be able to add records. It will also email the person when the record is added. This all works fine.
A further feature I need is that at various times some of the people may need receive an update email. Adding a filter string and requerying works fine too. The hitch is that indiviuals may be in the database more that once but should only receive one email. SQL does allow for 'DISTINCT myDB.email' to be inserted after the 'SELECT' and will therefore on result in the email address only appearing once.
I can't find how to add this to the requery filter to make it work. Does anyone have an idea.
Happy programming!!

What does this compiler error try to say to me?
Debug/Suza Utility.exe : fatal error LNK1169: one or more multiply defined symbols found
It can't be that I have declared two variables with same name...
