Hi,

Tq for your reply.

ACtually, I have one table : log. And it consist 4 fields.. Currently I'm having 20 records..
What I want to do is to have a struct / linked list..

So when I display the data, it will display like
-(field1, field2, field3, field4)

Why bother with a struct/list when you can display the data straight from the record set?

Are you using MFC?

device context vs GDI

wat is the difference between device context and graphics device interface?

See Wikipedia entry[^]

Taken from Above Link:

The Graphics Device Interface (GDI) is a Microsoft Windows application programming interface and core operating system component responsible for representing graphical objects and transmitting them to output devices such as monitors and printers.

GDI is responsible for tasks such as drawing lines and curves, rendering fonts and handling palettes. It is not directly responsible for drawing windows, menus, etc.; that task is reserved for the user subsystem, which resides in user32.dll and is built atop GDI.

A Device Context (DC) is used to define the attributes of text and images that are output to the screen or printer. The actual context is maintained by GDI. An HDC, which is a handle to the structure, is obtained before output is written and released after the elements have been written.

The device context is a GDI-managed structure containing information about the device. GDI contains a number of structures which you cna use to use generate graphical output for display, printers or other devices.

I don't know who in the living frock is marking your questions as "Good" (apparently none of your questions are that awesome to be marked as a good questions). I've noticed this a few times and I wonder if you have a split personality (another login) to "help yourself"?

Remember - the ones likely to provide you an useful answer do not care about if or not the query is marked as good.

Do you need to call CreateInstance() on the rs object before using it?

Hi all,

In an Standard combobox you can select the items from dropdown and as well edit it..

But in an owner drawn combobox after adding the items, u can only select from drop down.
What has to be done in order to allow owner drawn combo box to allow editing as standard control?? Roll eyes | :rolleyes:

Since combo box is customized,
now u need to make a customized edit box(CEditEx),
and when you double click the combo box a EN_UPDATE message is send to CEditEx, OnUpdateEdit.

You can only edit the combo box selection if the Type property of the combo box is set to Dropdown.
If the Type property is set to Droplist you can only do selection.

The current CWnd object will not become the owner of the Clipboard until the EmptyClipboard Windows function is called.

StartProcess/Inject DLL or Detours

Hi,

I was wondering if DetourCreateProcessWithDll is just equivalent to CreateProcess suspended, injecting the DLL, then resuming? Or is it doing something special in the background, and if so, does anybody have any code not dependent on the Detours library?

Thanks
