Hi,
I need to add soem custome HTML text in the New Message window of OutlookExpress.
I used the ObjectFromLresult and the IHTMLDocument for getting the HTML of that part whose class is Internet_Explorer Server.I wrote a function which will take the handle of the windows & returns IHTMLDocument.It is as follows
Public Function IEDOMFromhWnd(ByVal hWnd As Integer) As IHTMLDocument
Dim IID_IHTMLDocument As System.Guid = New System.Guid("626FC520-A41E-11CF-731-00A0C9082637")
Dim lRes As Int32
Dim lMsg As Int32
Dim hr As Int32
Const SMTO_ABORTIFHUNG As Int32 = &H2
If Not hWnd.Equals(0) Then
If Not hWnd.Equals(0) Then
' Register the message
lMsg = RegisterWindowMessage("WM_HTML_GETOBJECT")
' Get the object
Call SendMessageTimeout(hWnd, lMsg, 0, 0, SMTO_ABORTIFHUNG, 1000, lRes)
If lRes Then
' Get the object from lRes
hr = ObjectFromLresult(lRes, IID_IHTMLDocument, 0, IEDOMFromhWnd)
If hr Then Throw New COMException(hr)
End If
End If
End If
End Function
But the problem is that I'm not getting the HTML Body even I used the Script property of IHTMLDocument. In the interface variable its showing <undefined value="">. Then in the Script property call Error triggers as Object not reference to an instance of an object.
Please Help me
Its Urgent

I am just wondering if I'm headed in the right direction for this.
Could I use the Bitmap.Clone() to specify the area to grab out of an existing image?
i.e.
Point point = new Point(0 , 0);
Size size = new Size( 100, 50 );
Rectangle rect = new Rectangle( point, size );
Bitmap bitmap = new Bitmap.Clone( rect, System.Drawing.Imaging.PixelFormat.DontCare );
Will this get me the portion of the image that starts at 0,0 and has a width of 100 and a height of 50?
Any feedback will be greatly appreciated.

Well, that's what the documentation says. In most cases, I'd trust the documentation.

I'd go with Heath on this. As a little tip, if there is anything in the documentation that I don't quite understand I build myself a little demonstrator application (5 minutes work) to test my interpretation of the documentation. That way I can see if it works the way I think it does or not, and if not I now have a test platform to work from to see exactly how it is working.
I hope this helps.

I am trying to run the crystal reports custom tool on some VS/C# project reports and i am getting the error Load crpe32.dll failed. I tried registering it and got some error saying the entry point could not be found.
I know others have had this problem from some searching around but yet to find a fix for it.
My crpe32.dll is in Program Files\Common Files\Crystal Decisions\1.0\Bin

The has to do with the PATH environment variable, which Windows/Windows NT uses to find executables. If that directory is not in the PATH environment variable, then just specifying it like [DllImport("crpe32.dll")] will not work since it can't be found. Also, you should not hard-code this path in the DllImportAttribute because it may not be the same on every machine. Instead, in your installer add that directory to the PATH environment.
One other way is to use Environment.GetFolderPath with the Environment.SpecialFolder.CommonProgramFiles enum member to get the path to "\Program Files\Common Files" and use Path.Combine to append "Crystal Decisions\1.0\Bin", which should be the same in all cases (the "Common Files" directory is the last configurable directory for Windows in this case). You could then P/Invoke LoadLibrary, GetProcAddress, and FreeLibrary to load the proc address and execute it like a delegate (create a delegate with a matching signature).

I really hate that! Especially when company X add a PATH to its internal cygwin dir, and you just dont understand why cygwin just wont run the updated programs. (because it added itself to the start of the PATH and not the end, because for some strange reason PATH is limited to 255 characters, all others are 32k long AFAIK).

Are you talking about executing only one copy of the game at a time or only once per user login? The 'once per session' is what's throwing me...

Ok, look into Mutex's. A C# example and a class you could use can be found here[^] on CodeProject.

Hello,
Anyone here who have worked with this component? I'm having some problems. When I add a new document and editor control to the document, I want the new document to be the active document with focus on the editor. I can't get this to work.
Thanks in advance!

TabIndex is most likely the thing to set...

I'd like to be able to run the stored procedure sp_helpfile from within my C# program against my MSDE db. Is this possible?
I haven't a clue on how to set up a structure to hold the results of the command.
Any help would be appreciated.

You do it just like I told you to do for the sp_attach_db stored procedure. Look at the SQL docs for the names of the parameters and use this in the SqlCommand.Parameters.Add method as I did with the other stored proc.

Thanks for all of your help.
I just didn't know how I 'captured' the return values.
There is only one parameter to pass, the db.

Handle the SqlConnection.InfoMessage event. With each message printed by the server this event is raised. You can get the message from the SqlInfoMessageEventArgs that is passed to your handler.

Hi, all!
I have struggled too many hours now to find out how to connect to a
remote web service using w2k .Net soap over ssl.
I have received a certificate file from the publisher, xxx.pem which I divided in two, one xxx.crt (certificate) and one xxx.key (rsa private key).
Both base64-encoded. I have also received a passphrase for the private key.
But I just can't figure out how to put all this together, and successfully
manage to make a request from my C#-app.
How, for example, to include the private key with passphrase in the request???
I would be sooo happy for some answers... 
Regards
Christer

This... is a long road with many a winding turn... took me quite some time to get everything working correctly.
You fail to specify whether your C#-app is an ASP.NET web service client or a console/winforms web service client. I'll presume it's the latter as that's remarkably easier.
At either length it's easiest to use Microsoft WSE 1.0 enhancements[^] to fetch the certificate from the certificate store.
By default it is presumed that your client certificate is in the personal store of the current user (e.g. the one that is executing the application). If this is ASP.NET then as the user doesn't have a login profile the user doesn't have a personal store folder either and you need to carefully import the certificate to the personal store of the local machine.
The following code will get the private certificate from the depths of the certificate store:
<br />
byte[] certhash = { 50, 49, 239, 183, 249, 60, 36, 134, 129, 159, 39, <br />
226, 197, 70, 76, 1, 147, 237, 43, 217 };<br />
<br />
X509CertificateStore store = X509CertificateStore.CurrentUserStore(X509CertificateStore.MyStore);<br />
store.Open();<br />
X509CertificateCollection certs = store.FindCertificateByHash(certhash);<br />
store.Close();<br />
X509Certificate cert = certs[0];<br />
There are other ways to find a certificate than by using its hash value, but you can refer to the WSE 1.0 documentation for these.
Now, to add the certificate to the service call let's presume your web service object is Service1 then you add it fairly simply using:
<br />
Service1.ClientCertificates.Add(cert);<br />
It doesn't seem so daunting when you look at it like this, but it can take a lot of time to figure out given the.... usefulness.... of most code examples around. I think that's all it takes, good luck fighting the certificate mmc snap-in.
Hope this helps.

I've got a webservice that appears to be working. What I mean is that when I execute it in Vis Studio and bring up the web interface, it works just fine. However, when I try to use it in a program using SOAP I get this:
"An unhandled exception of type 'System.Net.WebException' occurred in system.web.services.dll
Additional information: The request failed with HTTP status 401: Access Denied."
I'm almost sure it's something with the Web Server (IIS), but I'm not sure what I've done that is restricting this access and how I can fix it. Any ideas?
Thanks for your help!

You need to check the access permissions on the directory in IIS and make sure that anonymous authentication is enabled for that virtual directory; otherwise, you must provide credentials (NTLM, Kerberos, BASIC and digest are supported by the FCL) using the Credentials property on your Web Service proxy that is inheritted by the WebClientProtocol class. See the documentation for the WebClientProtocol in the .NET Framework SDK for more information.

OK here is my dilemma, I have created a windows form (loginPage) that works fine. Now once they have entered their login ID & password I would like them to continue to the main menu form that was also created by the Visual Studio form Designer. However I cannot figure out how to switch control from the loginPage to the mainMenu form. The code is Application.Run(new loginPage()); for the loginPage. I can use the same statement with the main menu and it runs fine too, however I cannot figure out how to link the two so that only after the loginPage completes it runs the main menu.
Also the Main() function is in the .cs file for the loginPage form. Does this matter or should I create a controlling .cs program outside of the form to have Main() in it? Any preferences or coding style?
Im an old (10 yrs ago) C programmer and just getting back into VS programming.
Thanks in Advance,
Daniel Stagg

Simple enough... Your using the wrong page for Startup. Use the frmMain form for startup and have it call the login form. This will also give you the flexibility of putting code in your forms that, if necessary, can check to see if the user is logged in and, if not, call the login form from anywhere in your app.

Ok. So how exactly do I call the loginPage from the mainForm?
Basically I start the project with the mainForm and it gets Main() and the Application.Run() but where in the codeset do I call and how do I call another form?
Thanks.
