Try to add the extended style LVS_EX_DOUBLEBUFFER.
I discovered this solved some grid drawing problems when working on CGridListCtrlEx.
Though it introduced this funny drawing issue.
P.S. Also check that the dialog containing the CListCtrl has "Clip Children" set to false.

Thank you for your reply, I try to Add LVS_EX_DOUBLEBUFFER to the ListCtrl, but the VC6 doesn't know it at all.(And make sure the dialog "Clip Children" set to false)
I'm using vc6 under xp sp3, and with flatform sdk for xp sp2[^] installed.(I've download the Windows Server 2003 PSDK February 2003 Edition from MSDN too, but it can't be installed)
I've googled, it says define LVS_EX_DOUBLEBUFFER yourself as follow:
#define LVS_EX_DOUBLEBUFFER 0x00010000
I did so, and it compiles through, while the flick problem still exists.
Wait for your reply!

The LVS_EX_DOUBLEBUFFER requires that one set _WIN32_WINNT >= 0x501.
But if that doesn't help, then I have no other suggestions.

When using SHBrowseForFolder, I've noticed that when I try to expand a directory with a couple hundred child entities, it can take up to a minute to expand the node on the first attempt. Subsequent attempts are usually pretty fast.
Has anyone experienced these odd delays and found a way to prevent them? I guess I'm first looking to confirm that this might be a common ailment when using SHBrowseForFolder (either in general or when used incorrectly) and if so, what are some of the "don't do" and "should do" advice when using it for a generic folder selection dialog with nothing fancy intended with the filter?
Some relevant info...

when i pass value for the sfo.pFrom="d:\\Test\\*.txt\0" it delete the file. But i dont know where my software will install. I have also used to get the path by "GetModuleFileName (hMod, szName, sizeof(szName))" and i store path in a 3rd variable. When i used 3rd variable in "sfo.pFrom=3rd variable" It not works.
---------------------------------
char true_path[100];
//returns the path where .exe install---------
TCHAR szName [MAX_PATH];
HMODULE hMod = GetModuleHandle (NULL);
GetModuleFileName (hMod, szName, sizeof(szName));
Return_Path(true_path, szName); //returns the path with double slash like D:\\Test\\
//Remove the files from specified Foleder-------------------
SHFILEOPSTRUCT sfo;
sfo.pTo = NULL;
sfo.hwnd = NULL;
sfo.wFunc = FO_DELETE;
sfo.pFrom = true_path;
sfo.fFlags = FOF_FILESONLY | FOF_NOERRORUI | FOF_SILENT | FOF_NOCONFIRMATION | FOF_NOERRORUI;
SHFileOperation(&sfo);

Please post code for
1. Where you store the value in "3rd Variable"
2. And where you can SHFileOperation

Only string literals should have double backslashes.

Is this double \0 terminated?

Hi all,
I'm Trying to make some operation on a map. Unfortunately I have to make a massive use of pointers I'm not very expert In their use. I define the map in this way:
map<string,list><celement*>*> m_Layers;
In this map I want to change the key associated with two list. So The task I want to do is this:
if there is two entry one has a string called string1 and a list called list1, the other has string string2 and list list2. I want to change the key associated with the two lists so string1 is associated with list2 and string2 is associated to list1. I have thought to save the lists of interests in two extern lists and then to re-insert them with the key changed but I'm not able to erase the list present in the map because I use the pointer in a bad way the code I do (I Know that is wrong) is this:
<br />
string layerName = "layer1"<br />
map<string,list><celement*>*>::iterator mapIter = m_Layers.find(layerName);<br />
string levelToDown = mapIter->first;<br />
list<celement*>* listaToDown = mapIter->second;<br />
mapIter--;<br />
string levelToUp = mapIter->first;<br />
list<celement*>* listaToUp = mapIter->second;<br />
m_Layers.erase(mapIter);<br />
m_Layers.erase(m_Layers.find(levelToUp));<br />
pair<string,list><celement*>*> entry = pair<string,list><celement*>*>(levelToDown,listaToUp);<br />
entry = pair<string,list><celement*>*>(levelToUp,listaToDown);<br />
<br />

You are more likely to receive help if you post code that compiles, the following doesn't:
map<string,list><celement*>*>

I'll give you the same advice I do to others, and then you can ignore it also. Learn basics and fundamentals ( pointers is a basic in C/C++) before you move on to things like STL and developing applications.

Dear Friends,
Is there any API to get list of installed products in Windows?
Regards,
Krishnakumar

No. Even Windows doesn't know what's installed. You could just copy an app into a folder somewhere - the OS doesn't have to know anything about it.

I mean that, the list that is shown in the 'add/remove programs' in control panel.

That would be on HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

But that doesn't count as an "installation", does it?

Good Afternoon !
I have opened a handle of a COM port using CreateFile()
COMPortHandle = CreateFile ("COM1", GENERIC_READ | GENERIC_WRITE, 0,\
0, OPEN_EXISTING, 0, 0);
Now after that i do some other tasks.
Now i want to check the status of the handle i.e COMPortHandle
and close it if still opened, how to do it?
I do it in this manner, but i think it is not correct
if (COMPortHandle != NULL)
{
CloseHandle (COMPortHandle);
}
|

What do you mean by 'still opened' ? If you didn't close the handle yourself and if the CreateFile function succeeded, then your handle will still be opened. If you want to check if CreateFile was successfull, take a look at the documentation[^]: it returns INVALID_HANDLE_VALUE if it failed.

Hi
I want to have a scroll bar for a group-box control.
This is not possible bcoz the windows-os does not provide one , hence i was thinking of using a vertical-scroll control , but i was not successful.
Hence i thought of using a html page where in i can have a template and i can populate the values in the html page as i want programmatically.
I know this can be done in MFC , but i dont know whether the same can be done in win32 also.
Could any one help me

What I've done in the past is a bit complex, but a lot simpler than wiring up an HTML control - especially in Win32.
1/ Make a big overall window. Maybe a dialog box... The choice is up to you.
2/ Place a group control on it. This is just decoration.
3/ Place a vertical scroll bar next to, or just inside the right edge of the group box.
4/ Handle messages from WM_VSCROLL in your parent (eg) dialog.
5/ Create a child window taking up most of the space inside the group control. We'll call it PaneParent. This is blank, and does nething interesting except...
6/ Create a child window (call it Pane) inside the above child window. This Pane can be very large, and was also a modeless dialog box (with the WS_CHILD style set).
7/ When the scroll bar is used, move the Pane window about inside PaneParent. PaneParent will clip the Pane, so you only see a part of it.
Caveats - you'll also want the CONTROL and CONTROLPARENT styles set, to help the TABbing about.
None of this is easy, but it's OK if you break it into simpler bits. Make a dummy dialog with "I'm the top!", "I'm the middle!" and so on static controls on it until you have things working a bit more. But it's still easier than handling callback interfaces from an embedded browser control...
Iain.

Isn't a group box supposed to be static? How did you get this bad idea?
Why do you want to keep in so many things such that you will need a scroll bar? Not only will it require extra coding efforts, but it will look terrible. Ever heard of a tab control?

Yes.

No, not for attaching a scroll-bar to a group box.

How can we a tab control be useful,
