I am reading in an image (JPG) and I need to change the DPI from lets say 96 to 72. Here are the last two lines of code I am using to create the new image.
bmTarget = New Bitmap(ResizeWidth, ResizeHeight, PixelFormat.Format24bppRgb)
bmTarget.Save(NewPath, Drawing.Imaging.ImageFormat.Jpeg)
|
|
|
|
|
To fix the DPI of the image here is what I ended up doing.
After I created the bitmap image I used SET RESOLUTION -
BMTarget.SetResolution(intDpiX, intDpiY)
Then save the image

Hi
Just starting to look at .NET 2.0. Is it possible to get hold of the Application Event instance from anywhere in the application, guess it must be like a singleton?
Cheers

hi there all,
I am having a hard time doing this, the sample code is like this
Dim p As New Process
p.StartInfo.FileName = "C:\windows\system32\runas.exe"
p.EnableRaisingEvents = True
p.StartInfo.Arguments = "/user:myuser@mydomain notepad.exe"
p.StartInfo.UseShellExecute = False
p.StartInfo.RedirectStandardInput = True
p.StartInfo.RedirectStandardOutput = True
p.StartInfo.CreateNoWindow = True
p.Start()
Thread.Sleep(1000)
p.StandardInput.Write("mypass" & System.Environment.Newline)
p.WaitForExit()
p.Close()
p = Nothing
I was able to run services like this, doing other stuff from command prompt inside my application. but as runas require password which am trying to enter but it is not working.

I have a custom control that I created. It's a multicolumn combobox. It works great. My only problem is that I can only use ONE on my form. When I add a second instance of the control it will not do anything....only ONE will work. Anybody have an idea why that is?

Hi to all
can someone help me in writing code for Hibernating and Stand By (suspend) computer using vb.net code.
I have searched the internet a lot but don't found a reasonable answer to it.

I think but im not sure you will have to double check it
that there is some functionality in wmi. there is good documentation on the
microsoft website on how to access wmi from vb.net
good luck.

Look up the Application (for .NET) or App (VB 6) object.

You could use

Hi all,
I've just started programming in VB.net and am new to this forum. I've created a main screen for an application with several buttons, and grids.
I set the appropriate anchoring and everything works fine on me and my tester's PC monitor. I can resize the forms and use different redolutions.
However, when I run on my bosses Dell laptop, the right hand side and bottom of the screen are missing. No matter what I change the resolution to you can never see everything.
Has someone ever come across this issue before?
Any help would be much appreciated,
Dave

Okay this looks nasty. Real Nasty. So here's the code.
Its supposed to be three parallel color polygons but, it doesn't look like that.
This is the first time i'm using the gradient brush so, if any of the experienced Vb programmers could help me make it look neater than what it is, that would be appreciated.
Private Sub frmSplash_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint

Dim brGradient As System.Drawing.Drawing2D.LinearGradientBrush
Dim points() As PointF
'Defines the rectangle.
Dim clientRectangle As New System.Drawing.Rectangle(0, 0, _
Me.Width, Me.Height)
'Sets the Gradient Brush color for the red polygon.
brGradient = New System.Drawing.Drawing2D.LinearGradientBrush(clientRectangle, _
Color.Black, Color.Red, _
System.Drawing.Drawing2D.LinearGradientMode.Horizontal)
'Draws the points for the red polygon.
points = New PointF() {New PointF(0, 0), _
New PointF(0, 30), _
New PointF(ToSingle(Me.Width / 2.3), 320), _
New PointF(ToSingle(Me.Width / 2), 320), _
New PointF(ToSingle(Me.Width / 2), 295), _
New PointF(35, 0), _
New PointF(0, 0)}
'Fills the red polygon using the points and gradient brush.

'Closes the Gradient brush.

Replace ToSingle with CSng. You have created polygons. But those polygons don’t look like what you have expected. Try to change x- and y-coordinates of PointFs according to you preference.

What does CSng mean and what does it do?

Hi all,
1-I need to use custom paper size using crystal report in vb.net, how can I ?
2-Is there any way to create custom paper size and include it in printer paper size collection using printer properties at windows level ?
Thanks in advance
|

The first step is to see if your printer driver can support custom paper size settings - the PrinterSettings.PaperSizes property lists all the paper sizes supported by a printer and if this collection includes a paper size with .Kind = PaperKind.Custom then it can.

Hello,
Its supporting for custom kind . please let me know the details. and also let me know how to assign "CrystalObject" (object of .rpt) to "PrintDocument" object. Thanks

Yes , I found the way to add custom paper size in the printer collection of paper sizes.
Start -> Settings -> Printers and Faxes -> right click in the window -> Server Settings -> Create form ,give width & height and save the form with new name. now you have custom paper size in collection of printer.
Be sure,while creating form that you have selected the required printer driver.
Enjoy the Solution......
