I suggest you use Awesomium[^] instead of Including a web browser in WindowsFormsHost

Regards. Mehdi Ghiasi

Hello! I am developing a program. sometimes, i need to view something in a WebBrowser (using WindowsFormsHost or Awesomium) I want to glass somewhere of my window (in webbrowser) in winForms, I can make it black and it will glass inside browser (i think), but in WPF, I can't set a color inside webbrowser in black. So, How do I glass something in WebBrowser (using WindowsFormsHost or Awesomium) in WPF?

My server and sql server are different. (server of microsoft sql server is not localhost. it is sql.something.com) So, isn't there any performance problem?

Hello. I have opened a lot of cn.open() and cn.close() in my web application. for example when a page is loading, almost 10 connections are opened and closed. Whether it creates performance problems?

Hello, I want to load an JPEG image from file to a picturebox. I know that i can load using :

Picturebox1.image = image.fromfile("D:\MyImage.jpg")

and

dim b as new bitmap("D:\MyImage.jpg")
Picturebox1.image = b

but when I loading image using these ways, it loads bitmap format and uses more RAM space. (e.g a 3MB JPEG file uses 40MB RAM after loading) How Can I load the file with low RAM usage? UPDATE : Microsoft Paint also use 40MB RAM After open that file, but Microsoft Photo viewer use very low RAM usage. How can I load images with low RAM usage????? :confused::confused::confused::confused::confused::confused::confused::confused::confused::confused::confused:

Hi! I am using this BackTrack procedure that Fills a map.

Private Sub Fill(ByVal i As Integer, ByVal j As Integer)
If (i < 1) Or (j < 1) Or (i > FillM.Width) Or (j > FillM.Height) Then
Exit Sub
End If
If FillM.Pixel(i, j) = 1 Then
FillM.Pixel(i, j) = -1

        Fill(i, j - 1)
        Fill(i, j + 1)
        Fill(i - 1, j - 1)
        Fill(i - 1, j)
        Fill(i - 1, j + 1)
        Fill(i + 1, j)
        Fill(i + 1, j - 1)
        Fill(i + 1, j + 1)
    End If
End Sub

When The Map has a few pixels that have value 1, It works correctly. but when the map has many pixels that has value 1, It cause an StackOverflowException. How Can I resolve this problem and why .Net Framework 3.5 throw this invalid Exception???? :confused:

So how can I scale a 100x100 image into 150x150 ?

Regards. Mehdi Ghiasi

No! I have a monochrome bitmap in an integer array table and I want to resize it into a new array WITHOUT GDI+ or any Class that Resizes the image For me. I want to know How It Works!

Regards. Mehdi Ghiasi

Dear Friends. I want to resize a monochrome bitmap (every pixel can only contains 0 or 1) to another size (like 32*32 to 30*50). I can do it with GDI+ but I want to do it WITHOUT USING ANY CLASS LIKE GDI+. (only loop , for , if , etc.) How can I do it?

Regards. Mehdi Ghiasi

This Function Can help you! :-D

Public Function ResizePicture(ByVal sourceImage As Bitmap, ByVal newSize As Size) As Bitmap

    Dim Result\_image As New Bitmap(sourceImage, newSize.Width, newSize.Height)
    Dim Gr As Graphics

    Gr = Graphics.FromImage(Result\_image)
    Gr.DrawImage(Result\_image, 0, 0, newSize.Width, newSize.Height)
    Gr.Save()

    Return Result\_image
End Function

Then you can save the output of this Function By using ResizePicture(MyBitmap, New Size(100, 100)).Save(MapPath("/") & "/Images/MyImage.png", Imaging.ImageFormat.Png) Note: These codes are in VB.NET Language, but you can simply convert it to C# or any .NET language

So, How can I make a Color Picker Combo Box (Color Picker Drop Down list) for my WPF Application? (I can make it in my program with both XAML and code. but in a class, I haven't XAML, how can I Change ItemTemplate of ComboBox? I've made this control for windows forms with DrawItem Event.)
