I am using axMSChart objects to display charts in my VB .Net Windows Forms App.I am also trying to export them to a PowerPoint presentation which I automatically generate using Office Interop.However, when I use EditCopy to copy the Chart to the clipbord and paste it into PowerPoint, the color of the Edge of my Bar Chart is set to red for the firstSeriesCollection and green for the second one.
View 1 RepliesI have a database with testmarks of - lets say 30 students. I would like to print a distribution chart using Mschart. The values will be loaded into an array ChartData(30) The distribution chart X-axsis should range from 0 - 100 and the Y-axsis 0 to the average amount.... hopes it makes sence....

I was wondering if there is a way, I can hide the forms edge. By "edge" I meen the blue/gray half-transperrant edge. Like in the spotify login menu, for example. There is no edge.
View 3 RepliesI'm trying to draw some text using GDI (i.e. using a graphics object). It is done using the basic method of creating a path, adding a string to it and using a brush to fill it.
The only tricky part is that I need to apply a soft edge wipe to it. To describe what I'm trying to do better, I've uploaded an example done in photoshop: [URL]
What is the best way of achieving this? I need to be able to control the mask that is creating the soft edge - i.e. the position of the gradient, the width of the gradient etc.
Ideally I'd like to do it using the graphics object and not dipping into .dlls - but at the end of the day I'll do whatever it takes!!
Is there a way to feather the edge of an image?
View 1 RepliesI have a problem in detection edges in a picture. Im going to use this to make some recognition of pictures. I have found a way of doing Sobel filtering without the use of system.drawing.bitmat with BitmapSource.CopyPixels. I have posted code fore Sobel filtering here:
[Code]....
I have a function to do edge detection that works fairly good with one pass and without using a convolution filter. The only thing is that it will shift by one pixel the resulting image when I runt it from top to bottom and from left to right. I can live with that. Just a curious thing that I got when I ran it several times in a loop to see the effect of applying it several times on the resulting image.A deformed image appears at the beggining and then, bit by bit it splits appart and after shifting it the width of the original image I get a double image. I wonder how the computer keeps track of the first image and is able to separate the two after several iteractions.I know that in electronics you can have several signals in a circuit and you can separate them with frequency filters, or you can simultaneously download several files with the same modem aand the two computers will synchronize each one, but this surprissed me.
Here is a simplified version of my function
Private Function Preview(ByVal Thumb As Image) As Image
Dim bm As New Bitmap(Thumb)
Dim X As Integer
Dim Y As Integer

How do I curve the edge of a User Control?
View 1 RepliesI've got a usercontrol that's a simple rectangle with three labels on it. It's essentially triggered to give a caption to an image when the mouse is moved over it. As I feared, adding the control to the form (or any container on the form) restricts drawing the control to the region defined by the container. I tried increasing the region of the form and the container, but it still didn't draw outside the container.
So my question is: Is there a way to make the control display partially inside the container/form and partially outside it, or is there a better object type that will do what I want?

View 6 RepliesI would like my 'quit' button to appear in the bottom right hand corner of my menu screen, but it seems that every computer in the office has a different sized screen, different size ration (some are widescreen) and different resolution. When I deploy my program, the quit button may appear off-screen (the user has to scroll down to find it) or it may appear half way across the screen on a widescreen laptop for example. If I set my form to 'maximized', is there a way to position a button relative to the bottom right hand corner of the form? Also, on one maximized form I have two datagridview's side by side. Is there are way to automatically set each one to take up half of the available form width, so they fill the form nicely?

View 2 RepliesI've got a borderless form that I'm handling the MouseDown, MouseMove & MouseUp events to do the dragging and re-sizing which I have working just fine but I started thinking how neat it would be if I could have the borderless windows snap to each other and to the edges of the screen(s), this part I'm stuck on. I've got them snapping together just but and I've got it snapping to the edge of the screen but I have a dual monitor set up at home and I can't move it to my right side secondary screen with the code I have now. I'm attaching a sample VS2010 project with only the relevant code for this.Eventually I might add in the snapping to the desktop edge or to another note window's edge when resizing too, but that's not my focus right now.

View 3 RepliesI've spent hours searching the internet on this, and found a bunch of posts with similar problems, but none of the solutions I saw have worked for me, so bear with me. I have an application that's a couple years old that has a form with a chart on it(using mschart). Worked on my old development machine, and most users. Eventually some users started letting me know that the chart wasn't working for them. The chart was a minor feature, and I was unable to reproduce the problem, so it kept getting pushed back.

I am currently investigating vb gaming and have set up a test project to move an object; it moves fine. The problem is that when it reaches the edge of the form it continues to move and eventually leaves the form entirely. So my question is how do i work out if my object has touched the edge of the form?

I have several questions regarding the MSChart
View 5 RepliesHow do I do the following with an MSChart?Set axes to x: [0 - 1000] and y: [0 - 1].Show the gridlines when chart has no points.Disable auto adjusting of gridlines.
Note: Setting Axis(X/Y).(Min/Max)imum seems to have no effect if a point exists inside the bounds.
in runtime I can see that X-axis limits of my chart (minimum and maximum) are automatically changed as I insert points. That's nice. So I came to an idea to change that minimum and maximum values. It worked. But as soon as I wanted to return (at runtime) to auto I came across some problems. First I discovered that when auto scaling is activated this values are:

VB2005 - I have a form that has three DGVs. Two of these DGVs have data that I want to plot on a chart (currently testing with MSChart). Im struggling to figure out how to just plot the data from one DGV. The DGV has a column Time and Level which I want o plot as X and Y respectively. Can this be done directly with data from a DGV?
