this leads to a message where NMHDR is passed as one of the params but again one of the structures itself has a NMHDR type variable.
The newer common controls use WM_NOTIFY as opposed to WM_COMMAND for notifications. Notifications that use WM_NOTIFY require NMHDR structures to pass the notification information (think Notification Message HeaDeR). Notification messages that need to pass more information than the NMHDR structure can support pass structures that basically derive from (or begin with) NMHDR. That way, a common NMDHR is always available to the function that handles the message.
For example, the TVN_BEGINDRAG notification message is sent using WM_NOTIFY. That being the case, a NMHDR structure is required to be passed. But since the NMHDR structure does not support the required information of the notification message, a NMTREEVIEW structure is sent instead, which contains an embedded NMHDR structure as demonstrated here:
struct NMTREEVIEW<br />
{<br />
NMHDR hdr;
UINT action; <br />
TVITEM itemOld; <br />
TVITEM itemNew; <br />
POINT ptDrag; <br />
}
I hope that answered your question, instead of confusing you further!

Hi everyone,
I'm trying to distribute MDAC 2.5 with my application using Installer 2.0.
When the setup application is executed I want MDAC to be installed at the same time so my database app can run properly. I believe Installer 1.1 used to have a merge module that dealt with MDAC, but I can't find this in Installer 2.0.
Does anyone can any instructions or a reference for the best way to
distribute MDAC using Installer 2.0?
Thanks for your time,
Paul.

Anybody know how I can get SHBrowseForFolder to stop showing FTP sites? I am using CSIDL_NETWORK as the root path.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

If it is showing sites that the user specifcally added as a "Network Place" (which can be a FTP site), it sounds like the function is working correctly (as designed)...?
Although I have never tried to filter the sites that SHBFF would display (because that might confuse the user as that would not be the expected/default behavior), I would be suprised if there was an easy way to do it.
Peace!

Well, it doesn't consider those FTP sites to be valid as nodes (the OK button doesn't un-grey). It also allows you to browse the directory structure of the ftp sites.
It just seems strange.

That might have to do with the flags you have specified, for example BIF_RETURNONLYFSDIRS might cause that to happen.
Either way: I never suggested that MS' way of doing things (conventions) ever made sense!

You cannot write a MFC extension DLL and run it from other languages, e.g., VB, Java, MFC extension DLL's can only be used by MFC applications. If you need to build a language dependent component, you need to do so using COM.

COM is not s struct or class, it's a technique that introduced language independency on creating object models, if you do not have any background on using COM(or ActiveX), then I guess you need to spend a little time to actually learn it, COM is not such a simple thing that can be talked and mastered within this post.
There are quite some COM related articles in Code Project, just go to home page, find the "General" category on left bar and click on "COM/DCOM/COM+" link you'll get what you want. Good luck.

You will need to use COM

I don't really know that much about COM, other than it is language independent. I think it works like a DLL. I am pretty sure DirectX is in COM so it would be about the same way of using it.

Hello,
Can anybody tell me whereabouts vc++ version 6 stores the directories that are entered under Tools, Options, Directories?
Everytime I switch computer or add a new profile I have to add these in manually again, and I'd like to just copy a file or create them programmatically.
Thanks,
John

In the all mighty registry, under
HKEY_CURRENT_USER\Software\Microsoft\DevStudio\6.0\Build System\Components\Platforms\Win32 (x86)\Directories\Include dirs
|
|
|
|
|
Go to:
Tools --> options --> Directories and you can set and change them in there or in the registry

Anybody knows how to mannually send the WM_SIZE message to a window given the handle of that window.
In other words, what is the params for SendMessage(WM_SIZE, ...,...)?
|
|
|
|

LRESULT CALLBACK WindowProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
); wParam
Specifies the type of resizing requested. This parameter can be one of the following values.
SIZE_MAXHIDE
Message is sent to all pop-up windows when some other window is maximized.
SIZE_MAXIMIZED
The window has been maximized.
SIZE_MAXSHOW
Message is sent to all pop-up windows when some other window has been restored to its former size.
SIZE_MINIMIZED
The window has been minimized.
SIZE_RESTORED
The window has been resized, but neither the SIZE_MINIMIZED nor SIZE_MAXIMIZED value applies.
lParam
The low-order word of lParam specifies the new width of the client area.
The high-order word of lParam specifies the new height of the client area.
You can use the LOWORD, HIWORD, MAKELPARAM, or MAKEWPARAM macros to assemble the wParam and lParam paramters.

If you are interested, you can simply call SetWindowPos or MoveWindow to change the size of the window as well, and windows will take care of the message sending for you.

I'm writing an application which allows the user to set options in a property sheet with a few property page. The problem I'm having is with data validation. For each of the property pages, I've added some data validation when the user click the 'ok' button, i.e MyPropertyPage::OnOk()
The problem I'm having is that although the data validation is done, i.e
if (m_strName == "")
{
AfxMessageBox("Please enter a name!");
return;
}
when the OnOk() function exits from the return statment of the name check, the property sheet is closed?
I've tried commenting out
// CPropertyPage::OnOK();
to stop it called this method from the parent, but it is still called?
What I want is for the property sheet to stay modal, if the data entered is not valid.
Any help would be much appreciated.

Override the CPropertySheet::OnApply
and set the modified flag
and after test if u want to return
return true else return false.

I am writing a console program that will go to a database at certian intervals. Basically, I am trying to implement an automated email system for expired records. My question comes when trying to decide between using a Timer or just have the program use Sleep().
So I want the program to check the database every x number of minutes (probally every hour) and see if anything needs to be sent.
My restrictions are that it has to be able to run on win98 and higher.
Any suggestions. Right now I am leaning toward Sleep(), but I am not sure if that is a viable business app solution.
Thanks in advance,
