There is no BackColor or even Color property available for menu items. I am using Visual Studio.net and .Net framework 1.1.

I'll admit that I wasn't aware of .Net 1.1 not those properties available. My previous post was from using .Net 2.0. Are you required to use .Net 1.1?

That is a bummer because .Net 2.0 takes care of it.

I'm using the webbrowser control to login. How can I programmatically click on the login button if I don't know the name of the button.

<br />
<br />
HTMLDocument myDoc = new HTMLDocumentClass();<br />
myDoc = (mshtml.HTMLDocumentClass)wBrowser.Document;<br />
<br />
HTMLInputElement txtUser = (HTMLInputElement) myDoc.all.item("username", 0);<br />
HTMLInputElement txtPass = (HTMLInputElement) myDoc.all.item("password", 0);					<br />
txtUser.value = "ausername";<br />
txtPass.value = "apassword"; <br />
<br />

The login button has no name, so I don't know how to access it. Any idea?

Use a filtered UI Type Editor:

...
  
// Reference: System.Design.dll
using System.Drawing.Design;
using System.Windows.Forms.Design;
  
...
  
internal class MyFileNameEditor : FileNameEditor
{
  protected override void InitializeDialog(OpenFileDialog openFileDialog)
  {
    base.InitializeDialog (openFileDialog);
    openFileDialog.Filter = "JPEG Files (*.jpg)|*.jpg|All Files (*.*)|*.*";
  }
}
  
...
  
[EditorAttribute(typeof(MyFileNameEditor), typeof(UITypeEditor))]
public string PictureBoxBackgroundImage
{
  get { return m_bgImagePath; }
  set
  {
    m_bgImagePath = value;
    Image bgImage = Image.FromFile(m_bgImagePath);
    // should do some Image creation error checking here
    this.thePictureBox.BackgroundImage = bgImage;
  }
}

Hi..
I want to use the CmdLoadFromResource() method of ths speech SDK 5.1 to make the xml file that includes the Grammar embeded but i dont know how to use this method in C#.

This code shows how i used this method:

[System.Runtime.InteropServices.DllImport("kernel32")]
private static extern long LoadLibrary(string lpLibFileName);
private void button2_Click(object sender, System.EventArgs e)
{
this.objRecoContext = new SpSharedRecoContext();
this.objRecoContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(RecoContext_Recognition);
this.objRecoContext.State=SpeechRecoContextState.SRCS_Enabled;
grammar = objRecoContext.CreateGrammar(0);
int hModule=Convert.ToInt32(LoadLibrary("ReviewWinApp.dll"));
int langID=409;
grammar.CmdLoadFromResource(hModule,"tryRecog.xml","CFGGRAMMAR",langID,SpeechLoadOption.SLODynamic);

grammar.State=SpeechGrammarState.SGSEnabled;
grammar.CmdSetRuleIdState(1,SpeechRuleState.SGDSActive);

}

When i click this button i got the error:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in ReviewWinApp.exe
Additional information: The specified resource type cannot be found in the image file.

Could any one give me a C# code sample for using this method?

For along time no one answered my question in several forums in several websites Confused | :confused:

!

I thought that a lot of people have used Speech sdk5.1 Confused | :confused:

Painting and saving a PictureBox

I'm going to do a very very small painting program where I will load a picture on some kind of panel (I already managed that with a PictureBox). Then I will also let the user do a very trivial lines on the pictures. I have also managed that with:

Graphics g = pictureBox1.CreateGraphics();

My problem comes when I want to save the picture with the users paintings…

I manage to save the picture like this:

Image image = pictureBox1.Image;<br />
image.Save("C:\\bitmap.bmp", Imaging.ImageFormat.Bmp);

But I do not get the users painting saved…?

All tips are welcomed!!

Drawing onto a control via a Graphics object does not affect the image object displayed by that control. You will need to get a Graphics object for the Bitmap (via the Graphics.FromImage method) and draw whatever lines the user creates onto the in-memory image. Then, and only then, will the actual bitmap object be modified.

mike, thanks for you replies. Thing is that, i don't know for what type of classes or situation what type pattern need to be implemented. So, when you ask me "what classes are you using?" for this i don't have right answer, i mean, i am not doing any hi-fi coding. But trying to explore what type of class needs what type of pattern.

That is why I sent you there. It seemed like you could use some bootstrapping on the subject. Sometimes the answers one is looking for cannot be supplied as simply as Do (A) then do (B). Rather they require a contextual understanding before focusing in on a detailed level.

I want to use a .vb file in my c# project. Is that allowed? I added one and it does compile, but I don't know how to access the methods in the .vb file.

Can someone tell me if what I'm trying to do is even possible?

Thanks

Put the vb files in a seperate project in your solution and compile them as a seperate dll. Add a reference in your c# project to the vb project and you should be able to use all the classes in the vb project.

Wjousts option is a good one, but another option is to convert the VB file to C#. Google on VB to C# converters and find one you like (we have one also).
