When i create a band new WPF project without changing any code whatsoever does this on resize. It stays this way if i minimize or drag across monitors. Is this supposed to happen? It does this with all of my WPF applications so i set ResizeMode="CanMinimize" .
View 1 RepliesI just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

View 3 RepliesI'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.
The codes in the .cs files are all in black. For example the usual blue text keywords appear in black. Could this be to do with the intellisense not working either?
View 1 RepliesI'm currently making a huge project. So huge it is split into four separate applications. I want the form to fade to black once the user logs on and only fade up when the new program has fully loaded. I've tried various methods, such as having the second program write to a file on the C: drive, then have the first program wait until that file exists to fade out.Is there a more efficient way? My method isn't working... the form will fade to black, but you get a glimpse of the desktop just before the new program launches (both are full screen apps btw)
View 1 RepliesIn XP when you go to shut down, windows fades to black and white. I think that's a nice effect.How would i go about fading a color image (image box stretched - like a screen saver) to black and white...?
Has this ever been done? Is their a code snippet that already exsists?
I have a window that opens another window. The opening time of the second window is quit long because the application needs to build a complex interface. The annoying thing is that if the user clicks on the first window this become black as death! Is there a way to prevent this annoying behaviour?

[Code]...
I have a little piece of code which saves a certain Bitmap to a JPG image. The Bitmap is "composed like this" ( Ppiechart is a picturebox):[code]So After it is declared I start to do some drawing on this bitmap. And then I want to save it like this:[code]So this saves the image. But the problem is that the background of the image turns black when I open the file on my PC.The background of the Bitmap in the program itself is white. So does anybody have an idea what may cause this? Do I have to declare a color for the "mybitmap"?
View 4 RepliesProvided the following
vb.net Private Function isBlue(ByVal aRGB As Color) As Integer
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then
[CODE]....
I use it with the following:
vb.net Dim count As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
For x As Integer = 10 To 16
Works great. Takes a small square and tests for the blue color indicated by the aRGB value.
What I am trying to do now is test for all Black (as opposed to blue). I want to copy that isBlue Sub to a "isBlack" Sub and perform a like test, but I do not know what to use for this part:
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then explain those values and what changes to each one does?
I've edited the code some:
vb.net Dim bluepixels As Integer = 0
Dim blackpixels As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
[CODE]...
And in the sub I am testing for an R, G, and B value less than 3 (black should be all 0's) I'm still interested in how to manipulate those RGB values to test for other colors, or very specific hex colors.
i need a windows program (on visual basic express) to convert a list of images to black and white. then to send it to a microcontroller via ethernet. i dont know anything about vb at the moment so simple explanations and code would be great. in the meantime i will try learning vb. but i need this program quick.

View 3 RepliesI am trying to draw a black border around a ToolStripButton. This is the code I am using and it only draws the border on 2 sides. Dim clrMenuBorder As Color = Color.Black Dim borderPen As New Pen(clrMenuBorder)
Dim rect1 As New Rectangle(0, 0, e.ToolStrip.Width, e.ToolStrip.Height)
e.Graphics.DrawRectangle(borderPen, rect1)
My goal is to iterate through each pixel determining whether it is black or white. Ideally I want to do this one row at a time (so I can count the number of black pixels in each row). This is a bitonal image.I tried to get it started, but I don't understand what value(s) I'm supposed to be polling for. The following code takes a stab at it (i.e. makes a guess as to what value I'm supposed to check) and then outputs that value to a textfile.When I read the textfile, though, it doesn't look like anything useful.This code is an attempted modification of some code found in a CodeProject article.[code]

View 1 RepliesI want to make my system is the only system in the windows the user Can use it like games
since i want to make the background of my system is Black [code]...
I'm not sure if this should be here or in the Graphics subforum. Basically, I want to simulate the monitor(s) going black (it's an immature April Fool's Day prank). My initial thought was to create a borderless form that is the size of all the monitors with a backcolor of black. Then, slowly, increase the opacity of the form. This approach works great as far as the visual effect I'm trying to achieve...the problem is that it's a form. If the form is on top - while you can *see* windows below it - you can't interact with them. I'm wondering if there is a way to create the same visual effect without using a form so that the PC will remain usable while the monitor appears to slowly be getting darker?

View 1 RepliesIm working on in VB.net. Basically I�m trying to create a nice looking control that draws several PNG images (stars in this example) that light up as you hover the cursor over them. This side of things is working perfectly (see picture 1).
[URL]
The problem is trying to make it work using a transparent background for the control. I can make the control transparent by setting the controls back color and using Me.Setstyle to enable transparency support, but every time the image refreshes to show any lit stars it repaints over the stars again � making the shaded areas darker each time. This results in a horrible mess (see picture 2).
[URL]
Next I tried to clear the background each time a repaint occurs so that the stars are drawn on a blank canvas each time to stop this problem. The only way I know how to do this is to use graphics.clear(Color.Transparent) before my code to paint the star images. But this does not work as the control shows a black background instead of a transparent one (see picture 3)!

away the background to leave me with a transparent canvas to paint images onto? And is anyone smart enough to come up with a solution to this irritating issue?
I am a VB hobbyist and a new one at that. I am trying to create a transition effect in VB.NET 2008 when a certain form closes. The transition will take the form's current BackColor and slowly drop all the RGB values in it to 0 via a loop, obtaining a Fade to Black transition. I was able to come up with the code below. It works great. Maybe too great. It goes so fast that there is no transition. To the human eye it looks like the screen just went black instantly. Is there an easy way to enable a delay or pause in the below code to slow the loop down so that the end user sees the transition, and not just a quick jump to black?

View 6 RepliesWhen the dialog pops up, the screen dims down almost as if they overlapped the screen with a transparent black layer of some sort. This is easily accomplish able by creating a black form and having its opacity set to half and starting it maximized-which I'm already doing. The problem with this though is I need to do this within a form, so using a panel or anything is out of the questions since transparency really grabs the background image and not the actual controls underneath. Plus I feel if adding a form to another forms controls depletes it's ability to use it's opacity property.The form I need this in is my cash register. It is full screen but if my menu auto hides it still resizes. It has two parts, the order(panel to the left) and the payments(panel to the right). As you could imagine I want the payments portion blacked out until the order is capable of accepting payments(the payment due is greater than 0). Or I'm thinking it fallows the mouse, you mouse over the payments and the orders panel blacks out, and vice verse.
Plus I have tried googling this but no one seems to have the answer on other forums.. Everyone gets confused and the thread ends short with no solution. Apparently though experts-exchange has the answer, but wants me to pay... so no. Wish their site would stop showing up in my google results.But did have an idea of what I could do. My best guess was I could take a snap shot of just the panel I want to black out. Set it as the background image for that panel THEN use my overlay panel(back color sent to black) overlapping the appropriate section with it's transparency set to half.. But still I'm not sure how to take a snap shot of just a particular.control..
