I have a project, in which a user can click a button- even if he's using different program- that button in the program will simulate a keyboard shortcut and and use it in that current program he's using.

Does anyone know any good places to learn how to use WPF and Expression blend ?
View 1 RepliesI have a listbox that displays Shipment Items (custom class) that are formatted using a datatemplate (see below). There is a border element in the template (I am calling it a Gem) that displays which item is active (not selected) which will be the item to which products will be added.
template.png
There is a boolean property in the shipment class (Active) which is set in a click event handler for the Gem element. Normally the Gem is supposed to be dark as in the first image, then lit when active. I have a DataTrigger set up in the DataTemplate to handle the change in the color of the Gem.
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding Active}" Value="True">
<Setter TargetName="ActiveGem" Property="Background">
<Setter.Value>
[code]....
The Gems do not return to their unlit state (which they never were in the first place). They only remain lit.
How can I simulate a keyboard button click.For example how can I simulate the button 8 and 9 in another program outside my project form?

View 6 RepliesI know how to send keys using Sendkeys.Send("{RIGHT}") I even know how to use Send keys In a timer, to repeat the key press... But it's just a key press, and it lets the key up. So If I tried to put sendkeys.send("{RIGHT}") under a Timer, then it will press/release the Right Key. I don't want that. I want to HOLD THE KEY DOWN. Here's Some Code, that I know how to do that Simulates a Mouse Click, Left Down, AND Left Up. Mouse Click. Ok...? So here's some example code of how to Send a simulated Mouse Click.

I would like to know if its possible, and if so how, to use VB.NET to automate a keyboard shortcut. In the application i am developing, it receives email as a outlook addin and runs various checks and if those checks are positive it inserts information about the message into the database. But i want to be able to tell it that when the subject = "Keyword" to perform Ctrl+Alt+Up for, essentially a prank. However - I can't find anything on this anywhere, all i find is "Custom Short-cuts In VB.NET" and stuff about the KeyDown, KeyUp and KeyPress events.

In VB Classic, VBA and also in Visual Studio you can dbl click close to the left hand margin of a block of code and it will select the whole of the current block (sub, function etc). In Visual Studio this clickable area is adjacent to the line numbers on the left.Is there a keyboard shortcut that will do the same job? that is, select the "current block".

I'm trying to extract the icon from a shortcut (lnk file), but I end up with the shortcut symbol in the lower-left hand corner of the image. How can I extract a shortcut's icon without this symbol?
Here's the code I'm using:
Dim ico As System.Drawing.Icon = System.Drawing.Icon.ExtractAssociatedIcon("C:shortcut.lnk")
I'm trying to blend a few textures together to "bake" the final texture. Since I need the actual resulting bitmap, I don't think I can/want to do this using DirectX or OpenGL. I have:
- 4 Textures (RGB, 2048x2048): t0, t1, t2, t3
- 3 Alphamaps (ARGB, the RGB value is irrelevant, 64x64): a1, a2, a3
Here's what I currently do for each pixel (in simplified notation):
FinalColor = ((t0 * (1 - a1) + t1 * a1) * (1 - a2) + t2 * a2) * (1 - a3) + t3 * a3
This works fine, however, it takes forever, because I have to iterate over a 2048x2048 image pixel by pixel. Is there a more elegant way to solve this (i.e. using graphics.drawimage or something like it, but then, how?) How can I scale to Alphamap up with bilinear/bicubic interpolation (without having to do it pixel by pixel)? I currently use the original resolution, but that leads to rather visible transitions.
i would like to create a custom base class for some of my UserControls. Doing this in VS2008 is fine and compiles as expected, but when i edit the control in Blend 3 the base class in the blabla.g.vb is always changed back to System.Windows.Controls.UserControl.

View 3 RepliesI'm trying to do for a website. I've got a header banner that is 900px wide, and I want to display 4 random images across the banner. (I've got about 20 photos at this point, and I want the header to select from them.) I can get the code for the random selection, but what I'm looking for is a way to blend about 10 pixels near the overlap. If I have each picture exactly 225px wide, I get a "hard" line between the images. I'd like to make the images a little bit wider and soften the edge by overlapping and blending the images together. I have figured out how to get the image back to the web browser, but I don't even know where to start on trying to figure out the blending. Graphics really aren't my thing.
View 2 RepliesPreviously I used to piddle around with VB6 to develop a couple of personal projects. Following my upgrade to Windows 7, I've decided to piddle about with vb.net Express Edition 2010.If I wanted my VB6 application to blend in with the visual style of Windows, I would use the code and techniques described here. In short, I would use a Manifest file and a couple of calls within the application and most of the elements would look similar to the XP theme applied. If it was run on 2000, 95 or 98 then it would look like a standard Windows app. All was good.
Now I've moved onto vb.net, I've written a simple "Hello, world" application but I have absolutely no idea on how to make it look like the Windows 7 theme (eg. the font matches the system font and the widgets are styled correctly).Just changing the font is a hack and will look out of place on machines that are set-up differently or run a different version of Windows where the default font is different.How do I ensure my application matches the applied Windows theme irrespective of the version of Windows?
I want to do is blend two images together with a varying amount of transparency using a scroll bar/trackbar. In software I can do it by drawing an image into a picture box and blending another image on top with a varying amount of transparency but it is using gdi which of course is very slow. I would have thought that it should be very easy with fairly basic modern graphics cards but I am so bogged down with examples of how to draw fancy rotating rectangles etc with direct x that I can't see through it all. Should I look at directdraw, direct3d, opengl?

View 1 RepliesI need to submit a project tomorrow, and the topic is WPF using XAML. We are using VB by the way. Now I am still a beginner at programming, so I needed help. I've got a ton of WPF and blend tutorials open in tabs in my browser, but I have no idea where to start, and no idea for a project. I asked my tutor and he said he'll be checking our understanding of XAML, and creating an object using XAML as well as the other way round.
I stumbled onto some tutorials of media players main in WPF, and I decided to go with it. But because I have never used blend or WPF along with XAML before, I don't know what to do, if say I make a button in blend with effects, so that I may add coding behind it in VB. Please help me out. I've got like 15 hours before I have to submit.
