Try applying a RotateTransform to the Graphics object.

What I am trying to do is take an Image (either in the picture box or a saved bitmap) and resize it to my fixed dimensions. Having some trouble with it and the snippets that I've been looking at aren't really helping.
Thanks in advance

Well, first load the Image and then use the GetThumbNailImage Method to resize it. So, if your Image object is named img, then,
resizedImage = img.GetThumbNailImage(width, height, Nothing, IntPtr.zero)
Specify the Width and Height in Pixels, and you'll get your New Image in resizedImage with that height and width.
Hope this helps.

i had made a project on wallpaper changer, and it is working very well.
the code
PictureBox6.Image = img5.GetThumbnailImage(117, 121, Nothing, Nothing)
will made the picturebox as thumbnail of the size demanded.
and if you wnat to make the size of the picture according to the resolution ofthe desktop than check this out....
private static void ConvertSourceFileToBmp(string sourceFilePath, string tempBmpFilePath, ScaleStyles scaleStyle, Color backColor)
{
Image sourceImg = Image.FromFile(sourceFilePath);
if (scaleStyle != ScaleStyles.BestFit)
{
sourceImg.Save(tempBmpFilePath, System.Drawing.Imaging.ImageFormat.Bmp);
}
else
{
//get the dimensions of the screen
float H = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;
float W = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
//get the image dimensions
float h = sourceImg.Height;
float w = sourceImg.Width;
//dimensions of target
float targetHeight = -1;
float targetWidth = -1;
//find the appropriate height and width
if (H / h >= W / w)
{
targetWidth = w;
}
else
{
targetHeight = h;
}
if (targetHeight == -1)
{
targetHeight = (H / W) * targetWidth;
}
if (targetWidth == -1)
{
targetWidth = (W / H) * targetHeight;
}
//create a new image with the default back color with the scaled dimensions w.r.t. image and screen
Bitmap bmpImage = new Bitmap((int)targetWidth, (int)targetHeight);
Graphics g = Graphics.FromImage(bmpImage);
SolidBrush backgroundColorBrush = new SolidBrush(backColor);
g.FillRectangle(backgroundColorBrush, 0, 0, bmpImage.Width, bmpImage.Height);
//layout this image in the center
g.DrawImage(sourceImg, Math.Abs(targetWidth-sourceImg.Width)/2, Math.Abs(targetHeight - sourceImg.Height)/2, sourceImg.Width, sourceImg.Height);
//save it as bmp
bmpImage.Save(tempBmpFilePath, System.Drawing.Imaging.ImageFormat.Bmp);
//dispose stuff
backgroundColorBrush.Dispose();
g.Dispose();
bmpImage.Dispose();
}
sourceImg.Dispose();
}
private static void SetRegistryKeyForWallpaper(string keyName, string value)
{
RegistryKey deskTopKey = Registry.CurrentUser.OpenSubKey(@"Control Panel\Desktop", true);
deskTopKey.SetValue(keyName, value);
deskTopKey = null;
}
if this could'nt help you,plz let ne know your problem in detail,and what actually yo want to do.
waiting for ur reply...

Thanks for the replies that I recieved. While they helped inresizing the image it wasn't really what I was looking for. I wanted the image resized then saved as the new size. The two snippets suggested simply resized the view of the image. I did, however, find this bit of code which worked nicely after I tailored it a bit.
Dim syspath As String<br />
syspath = Environ("systemroot")<br />
<br />
Dim bm As New Bitmap(picLogo.Image)<br />
<br />
Dim myX As Integer<br />
<br />
Dim myY As Integer<br />
<br />
myX = Val(148)<br />
<br />
myY = Val(119)<br />
<br />
Dim thumb As New Bitmap(myX, myY)<br />
<br />
Dim g As Graphics = Graphics.FromImage(thumb)<br />
<br />
g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic<br />
<br />
g.DrawImage(bm, New Rectangle(0, 0, myX, myY), New Rectangle(0, 0, bm.Width, _<br />
bm.Height), GraphicsUnit.Pixel)<br />
<br />
g.Dispose()<br />
<br />
<br />
<br />
thumb.Save(syspath & "\system32\oemlogo.bmp", _<br />
System.Drawing.Imaging.ImageFormat.Bmp)<br />
<br />
bm.Dispose()<br />
<br />
thumb.Dispose()<br />
<br />
Me.Close() 'exit app<br />
If someone knows of a cleaner/smaller way of doing this feel free to suggest it

I've been trying to translate the WM_KEYUP messages returned from the callback of a SetWindowsHookEx keyboard hook.
Whilst most examples I can find on the net are in C++, I'm having a hard time finding / converting this into VB.
I have the API declarations for the ToAscii, GetKeyboardState etc., just need a ready to go piece of code to paste into my application.
Thanks in advance
Code snippet attached of the callback ...
Private Function KeyboardCallback(ByVal Code As Integer, ByVal wParam As Integer, ByRef lParam As KBDLLHOOKSTRUCT) As Integer
If Code >= 0 Then
If wParam = WM_KEYUP Then
'I need to translate the lParam.vkCode and lParam.scanCode into ascii or something useable for a few keys like carriage return, backspace etc.
'32 to 127 = regular characters
'13 / 10 = carriage return in log file
'9 = [TAB]
'8 = [BACKSPACE]
'127 = [DELETE]
'other ascii codes not interested, likewise anything above 128, I don't care about
'how do I use ToAscii and GetKeyboardState ?
End If
End If
Return CallNextHookEx(KeyboardHandle, Code, wParam, lParam)
End Function

Jijo,
I have been fighting with a similar problem for months. Nothing seems to work for me but this code might give you a start.
Set AppExcel = CreateObject("Excel.Application")
AppExcel.Workbooks.Open FileName:="Put Your Excel Address Here.xls"
Hope you have better luck than I have been! Garner

Hi,
I'm trying to declare a DataRow array. But it's not working.
I want to use it to create a DataTable. I do not know how many datarows I want to add to my DataTable, so I want to declare a variable number of datarows.
Can someone tell me how to make this work?
Thanks,

Standard question #1:
What do you mean by "not working"?
---
b { font-weight: normal; }
|
|
|
|
|
I'm sorry. "Not working" is are not the right words.
Actually, I don't know how to declare it. And afterwards use it...

I am not really sure what you are asking, but try using Date.Now.ToString("mm/dd/yyyy") and compare this string to the date in your text box
