Hello There!
Let Consider the m_strEditBox of type CString which is the variable associated with the EditBox from which you want to get text input by User.
now! For Getting Text in to your Variable i.e. m_strEditBox
Call UpdateData(...); with TRUE as Argument
this->UpdateData(TRUE);
this will fill your m_strEditBox with the data entered by user
.................
Now do anything with the m_streditBox variable i.e. broke in token etc etc.
..................
now if you want to update the data back to Edit Box
just again Call UpdateData(...); with FALSE as argument
i.e. UpdateData(FALSE);

Thanks.
how do I display my output in some other edit box now .
|
|
|
|
|
Now let the m_strEditBox1 of type CString is associated with some other edit box where you want to put data.
//now give value to m_strEditBox1
m_strEditBox1="Codeproject is great";
//Update the data back to edit box call UpdateData
this->UpdateData(FALSE);

CEdit m_MyEditControl;
CString m_csEditControlText;
// fill in edit field immediately, bypassing dialog's UpdateData call...
m_MyEditControl.SetWindowText(m_csEditControlText);

check msdn for GetWindowText().

Just curious to know, Where you got the information that the GetWindowText() function will return the edit text ?

void CWnd::GetWindowTest( CString& s );
well duh ( sorry, it's 3:00 am, and I'm not asleep ), you pass a reference to a CString to GetWindowText...
CString myString;
MyEditBox.GetWindowText( myString );

As Maximilien said, you give the GetWindowText() a String, and it will fill it for you.
As for getting the right variable to call GetWindowText() on, you can use the ClassWizard to make a so called Control Variable for you. Thats a variable of the Type of your control (probably CEdit) and you can use it without resorting to the complicated and confused UpdateWindow()-stuff.
You just need to set one hook in the Class Wizard.

I have the following code adding to a CListCtl on a dialog box named m_cList, but for some reason the first element I add doesn't show up:
<br />
LRESULT CRTFParseTest1Dlg::OnCreateListGroup(WPARAM wParam, LPARAM lParam)<br />

CStringArray sa,<br />
sa1;<br />
CString sFormat;<br />
<br />
for(int a(0); a < 3; a++) {<br />
sFormat.Format("Column %d", a);<br />
sa.Add(sFormat);<br />
}<br />
InsertColumns(sa);<br />
sa.RemoveAll();<br />
<br />
sa.Add("Item");<br />
for(int b(0); b < 5; b++) {<br />
sFormat.Format("Group %d", b);<br />
AddListGroup(b, sFormat);<br />
<br />
for(int b_0(0); b_0 < 2; b_0++) {<br />
sa[0].Format("%d:%d", b,b_0);<br />
AddItemToGroup(b_0, sa, b);<br />

Any idea how to make it work?

your code displays 10 elements and is working. starting from 0.0 to 4.1 . Which is the exact string you feel is missing as per the code.

The code to create them does work, but in the list the groups don't have the right elements in them. Here is what I get in my list control:
Group 0
-0:1
Group 1
-0 <--This should be in group 0
-1:1
Group 2
-1 <--This should be in group 1
-2:1
Group 3
-2 <--This should be in group 2
-3:1
Group 4
-3 <--This should be in group 3
-4:1 <--Where did 4 go? It doesn't show up in the list.
The problem is the first element in each group shows up in the preceeding group, which is probably why 4 does not show up. I can't seem to figure out why this happens and how to fix it. Got any ideas?

i have developed one console application in VC++. It contains following code;
system("\\\\COMP1\\shared\\app1.exe");
it tries to execute app1.exe, which resides on remote machine. It works when run as a console application.
I have created one service MyService. This service calls the above console application.In this case system() fails to execute app1.exe .
please help me.

service by default runs as "SYSTEM" user. Suggested way is to make service run as
a different user, who has the permission to access the "COMP1\\shared" folder. Open "SCM->dbl clk MyService->Logon_tab" change the user.

2 questions
1) is wininit.ini in windows directory or system directory?
2) how to write keys to a secton of wininit.ini file?
thx
includeh10
|
|

|

1) The \windows directory
2) It's an INI file, however for deleting it's harder because the format is:
[rename]
NUL=C:\temp\file1.exe
NUL=C:\foo\file2.exe and so on. You can't use WritePrivateProfileString() because the second NUL line would replace the first. You need to read the whole file in, modify it, and write it back out. I know I saw an MSDN article with code to do this, but I can't find it now.

hi mike,
your comment is the same as doc in VC doc about function MoveFileEx().
i write this pice of code manually to ininit.ini, but none of files are deleted after reboot.
headache.
includeh10
|
|
|
|
|
to delete an dll (COM) file programmatically which is used by system.
MoveFileEx() can do that if reboot system by the function is unavailable on win95/98.
is there a function (reboot is fine) for win95/98 which can delete a file used by system?
thx
includeh10
|
|
|
|
|
Dosen't win95/98 allows you to delete the COM dll if its loaded also ?

Hi there!
in 95/98 system you can write in WINinit.ini for deleting the file at reboot.
I have seen article relating to this in CP ,but can't able to find that today.
I think you have to find that your self

is there any way that i can write a generalized program to dynamically detect
any number of Dll in a folder and statically link them.
upto now i have my application that statically links and implicitly loads the dlls. i will detect the newly added dlls and keeps information in File.The infor
mation in the file and registry information is enough. The problem is how i can
my appliation understand the new dlls, how can oi include the headerfiles.
IS THERE ANY POSSIBILITY
|
|
|
|
|
As far as I know, this isn't possible.
Static linking implies that all code be known and identified at link-time, static linking is effectivly dynamic linking with hidden 'glue' that uses staticly bound stubs to dispatch to the dll.
This is possible and very simple to do with dynamic linking provided your class heirarchy supports it.

Can someone tell me the basic difference between a vector,list and dqueue. just the basic difference is appreciated.
|
|
|
|
|
They all have slightly different performance specifications and operations which make them suitable for different tasks.
std::vector is a dynamic array
std::list is a doubly linked list
std::deque is a hybrid container which is like a list of vectors (from memory)
By default, use a vector.
If you need to add to the front and the back, use a deque.
If you need to be able to insert/remove efficiently from the middle of a container, and never need random access use a list.
