View 2 RepliesI recently changed from vb 2008 express to vb 2010 express and converted a project I was working on to vb 2010. After conversion I added a lot of code and all worked well. Now I want to add some shapes from the vb power pack tools and I get the following error:
---------------------------
Microsoft Visual Basic 2010 Express
---------------------------
Failed to create component 'OvalShape'. The error message follows:
'System.InvalidCastException:
[A]Microsoft.VisualBasic.PowerPacks.ShapeContainer cannot be cast to [B]Microsoft.VisualBasic.PowerPacks.ShapeContainer.
Type A originates from 'Microsoft.VisualBasic.PowerPacks.Vs, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' in the context 'Default' at location
......
How can I recover from this?
I am using the PowerPack and trying to change multiple ovalshape size, I have used the following code for changing multiple labels,
For Count As Integer = 1 To 100
Me.Controls("Label" & Count).Text= "Hello World"
Next Count
If I do the same for OvalShape, assume I have OvalShape1, OvalShape2.... OvalShape100
For Count As Integer = 1 To 100
Me.Controls("OvalShape" & Count).Size = New System.Drawing.Size(20, 20)
Next Count
The above throws error when executed.
How to change the size of RectangleShape or OvalShape at runtime?

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?
View 6 RepliesIve been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.

I am trying to edit an image. I can open the image with Picturebox1.load(mypicture)
I can change the pixels/edit the picture by Dim img as new bitmap(picturebox1.image)

now here is the weird part. When I save the image the filesize INCREASES..but the picture dimensions are the same Example... TEST.PNG 1.3KB, when opened up via picturebox/saved the image is now 2.3KB
not sure why...i even though I specify system.drawing.imaging.imageformat.PNG
samething with JPG... it actually SHRINKS it evenmore.. example 88KB jpeg.. saved as jpeg is now 47.7KB...
I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

View 1 RepliesI'm trying to get the image's name from a imagelist..[code]ofcourse that "name" doesn't exists, and I'm trying to find out what another correct way to get the name of that image.
View 1 RepliesI have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

I'm playing with creating thumbnail images for my photo website using VB rather than Photoshop.[code]However, I'd really like to be able to crop images to a square shape - same width and height - from a starting image that might be 1000 pixels wide x 667 high, 500 wide x 750 high or already square and around 750 x 750. In other words, crop a square from the central area of a jpeg image, irrespective of it's exact size.

The solution that was offered was to use the Easy Screenshot class that is in the code bank.While this solution works, there are obvious drawbacks. I'm trying to fully automate this program, and needing the window to come to the foreground, even momentarily, defeats the purpose of it.Is there another way to get the image held in a picture box of a 3rd party application?
