i have also copied this file in my application's bin dir but again same problem ,it gives me following error when i make setup ...

ERROR: 'shdocvw.dll' should be excluded because its source file 'C:\WINDOWS\system32\shdocvw.dll' is under Windows System File Protection.

please if possible give me the solution

Generate the assembly with a different name, like Interop.SHDocVw.dll, which is what VS.NET would call it if you did imported the typelib in the shdocvw.dll library by adding a COM references in the Add Reference dialog.

If you're using tlbimp.exe, use command line switches like this:

tlbimp /out:Interop.SHDocVw.dll %WINDIR%\System32\shdocvw.dll

Type the following for more information about the switches available for tlbimp.exe:

tlbimp /?

You should also consider signing this and keeping it in a global directory that's easy to reference. If you do sign it, you can install it in the GAC. Believe me, this is a common assembly in many applications, except that everyone signs it with a different key, if they sign it at all (production code should always be signed to help protect the integrity of the product, not to mention it's so easy there's no excuse not to).

You can convert the components of SHDOCVW.DLL to ActiveX components.

NOTE: This requires Visual Studio .Net!

Copy the file: C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin\AxImp.exe in any directory.
Then make a shortcut (or a link [I don't know the English word for it Confused | :confused:

]) to this file.
Type this text in "target" field:

"[location]\AxImp.exe" [path]

[path] is the dll file to convert.

After doing that in the directory will be following files:
AxSHDocVw.dll and SHDocVw.dll !

Reference the file AxSHDocVw to your project.
An instance of a Browser Object looks like this:
private AxSHDocVw.AxWebBrowser axWebBrowser1;
You can use this Object like any other Windows Components.

If there are any questions left, let me know!

Good luck!

No it does not, Aximp.exe comes with the .NET SDK, which is free to download. Also, if you have Visual Studio .NET, you can easily add the web browser from the toolbar and it will automatically generate the interop assemblies for you.

Why go to all that trouble to execute aximp.exe or any SDK utility for that matter? Simly add "C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin" to your PATH environment variable in your System control panel. This environment variable is used to resolve executable paths when you run a problem. If it exists in the PATH, you don't need to type the full path to the executable file. It's also used by the executable loader to locate DLLs that need to be mapped into the process space.

While you're at it, also add the Framework directories (ex: "C:\Windows\Microsoft.NET\Framework\v1.1.4322" so you can use the compilers and the assemblier without typing the full path. Do this for a good developer workstation setup. I make great use of it because I really don't use VS.NET for most code samples.

And Nick is right, you don't need VS.NET for the Framework SDK. The .NET Framework SDKs are freely downloadable installations separate from the Framework installations that provide everything you find in "C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK" on your machine, since VS.NET just includes the Framework SDK installation.

move form

if i have a mdi child form within a mdi form and i want to restrict the child so it can't move outside of the parent form, how would i do this? this is what i have but when i'm moving the child form i get some weird painting effects.

protected override void OnMove(System.EventArgs e)<br />
{<br />
    if (this.Left <= this.Parent.Left)<br />
        this.Location = new System.Drawing.Point(this.Parent.Left, this.Location.Y);<br />
    if (this.Right >= this.Parent.Right - 3)<br />
        this.Location = new System.Drawing.Point(this.Parent.Right - this.Size.Width - 4, this.Location.Y);<br />
    if (this.Top <= this.Parent.Top)<br />
        this.Location = new System.Drawing.Point(this.Location.X, this.Parent.Top);<br />
    if (this.Bottom >= this.Parent.Bottom - 3)<br />
        this.Location = new System.Drawing.Point(this.Location.X, this.Parent.Bottom - this.Size.Height - 4);<br />
    base.OnMove(e);<br />
}<br />

I'm not sure of some auto-magical way to accomplish this, but what you're doing is roughly what needs to happen somewhere down the call stack anyway. So, what kind of "weird painting" effects are you getting? Is there a lot of flickering, or is something else going on (like your VCR time gets reset Smile | :)

my vcr time is just fine but what i am getting is bad flickering. it flashes back and forth from where the form is suppose to be to where i am trying to put it. so is there a way to disable the mouse down or the form painting when it reaches the boundaries of the parent form?

thanks,

Heath Stewart26-Mar-04 22:32

I see. The form is still trying to go where you put it but when your code executes it tries to put it back to where you want it to be. You definitely don't want to stop painting, but you could try to override OnMouseMove and do NOT call base.OnMouseMove if you've reached your MdiParent's extents. This might work, so long as it cancels the underlying WM_MOUSEMOVE notification message handler. I highly doubt it since the MouseMove event is fired in response to the mouse moving. In this case, try overriding the child form's WndProc and before calling base.WndProc, handle the WM_MOUSEMOVE notification message (0x0200) and just return without doing anything if you've reached your MdiParent's extents.

wow, you lost me there. i don't know the language well enough to do what you're suggesting. i guess i'll just put it back to the default, where the form is allowed to go off screen. thanks for you help though, i really appreciate it.

Consider this a learning experience, then! Smile | :)

Have you ever done MFC or even just straight win32 programming with the Windows Management APIs? If so, you know about all you need to know (undering marshaling and P/Invoke will be required a little, too, but nothing extraordinary.

In your class for which you want to override the behavior, just do something like this:

protected override void WndProc(ref Message m)
{
  if (m.Msg == WM_NCMOUSEMOVE)
  {
    // Determine if window should move. If not just return.
    if (Left <= MdiParent.Left || ...) return;
  }
  base.WndProc(ref m);
}
private const int WM_NCMOUSEMOVE = 0x00a0;

Like I said, though, I'm really not sure this will work, although I have more hope for this than for override OnMouseMove since that happens in response to the WM_NCMOUSEMOVE notification message and can't be canceled.

This little line just determines if your window can move anymore and throws out the message if it can't. You might also notice I changed WM_MOUSEMOVE that I posted before to WM_NCMOUSEMOVE for the non-client area of the dialog...what was I think?! Smile | :)

i'm always ready to learn. unforunately i havn't worked with MFC or windows management APIs. i've tried everything i can think of to get this to work and i tried playing around with the code you gave me but it seems like that code executes at odd times. i had it update a textbox when it drops into the if statement before it returns and it doesn't update it in the same spot everytime, it's weird. i would like to know where you got the WM_NCMOUSEMOVE = 0x00a0 though. what does this mean and why is 0x00a0 an int?
if anyone out there has any input for constricting the movement of a form to stay within it's parent that would be great.

thanks,
Rob Tomson

I got the constant value from winuser.h, the header with most of the constants defined for the Windows Management and related APIs. You can easily find these if you download and install the Platform SDK, which does get installed by default with VS.NET (though it's not pretty old).

Why is 0x00a0 an int? You've never seen this notation? It's a simple hexidecimal notation, or base16, which is 0123456789abcdef. So, 10 (a) * 16 = 160. int (Int32) is only a 32-bit number, as is 0xXXXX (four alphanumeric characters).

I typically keep the hexidecimal notation that's defined with the C/C++ headers from the PSDK, though, because it makes lookups easier and lets me format my code better.

Ado.Net using c#

How can I get The all user defined table name from a MSAccess Database using Ado.Net(c#)

This is Jitendra

Heath Stewart26-Mar-04 20:15

26-Mar-04 20:15

You can use a query like the following:

SELECT Name
FROM MSysObjects
WHERE Type = 1 AND Name LIKE "MSys%"

All the Access system tables start with "MSys", so unless you expect user tables to begin like this the query above should work fine.

Thanks FCriend

Heath Stewart31-Mar-04 3:04

There is no "MSys" table, but many tables that start with "MSys", which is why I said "MSys*", like a wildcard match. Make sure you specify a proper table and that the credentials (username and password) you log in with have administrative privileges (like the "Admin" user).

Also, don't say things like "the permission Exception". If you need help, be specific and say SecurityException or InvalidOperationException or something like that, along with the exact exception message. There's many things that can go wrong in an application, even in specific blocks of code.

an SMTP problem

I write a winApp to send EMAIL. Since the server needs to authenticate, so
I need to use TcpClient rather than SMTPMail class. But the problem comes.
Following the DATA tag, I send strings like these:

"Subject:IP Notice"+CRLF;
"This is your IP."+CRLF+"."+CRLF;

But when I receive the mail, only subject was appear and there was no mail body. If I do it in this way, sending the follow strings:

"Subject:IP Notice"+CRLF;
CRLF;
"This is your IP."+CRLF+"."+CRLF;

Then the body exists.
Please do me a favor. I don't know why. Thanks a lot Laugh | :laugh:

This is what the SMTP protocol requires, as well as the HTTP protocol for that matter. You must have to carriage-return, line-feeds after the headers.

See RFC 821[^] (SMTP) for details.
