is there an easy way to stop the changing of colours when you disable a control. i want the controls to look normal just not do anything if you try to use them would have thought there is a global setting or something??

whenever i load the image, i have to load it a second time to get the colour, or if i load a new one, i get the colour from the previous image, any ideas as to why?
I've got a bar chart on my form which when I click a button, it populates with some data showing the clients net position, which is their assets vs their liabilities. This is shown on a year-by-year basis, so the graph will go up or down accordingly. If the graph goes into negative, or is negative at any stage, I would like it to turn red, and leave the positive values green. I have no idea how to do this, or even where to start looking into the properties. I'm still new to using the charts. How can I make the x-axis labels in increments of 5 from 0, instead of increments of 5 from -1?
View 3 RepliesI have an VB.net application in which I have imported the MSchart control 6.0. It draws all the bars in the same colour. I want to have each bar in different colour. I want bars of the same series to be so. There is only one series of data.

The following procedures sorts a listview column based on what the tag is, 'Numeric', 'String' or 'Date'. When you click on the column header the sort procedure kicks in. On the first click it will sort ascending and on the second click it will sort descending.
My problem is that when I click a second time it won't sort descending but re-sorts ascending again.It appears when the sortorder is passed to the ListViewColumnSorter.vb classes it changes back to ascending even though it's called as descending. I've bolded the offending variables using a Numeric search.Now here's the really iritaing thing, I have exactly the same code in another application and it works perfectly?
Private Sub lvwResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvwResults.ColumnClick

This is my code for a trial application. The code is pretty basic but what i couldn't figure out was how i would be able to prevent users from changing the date to extend the trial ("error" i would be getting).
There is an older version of the software which works fine on all of our deployment platforms, but the version I am trying to push out is working fine on 32-bit desktop installations, but is crashing-and-burning when it attempts to access Crystal Reports and Informix installed DLLs on a 64-bit machine, running terminal server sessions (yeah, I know, could I change anything more about the deployment platform?)One of the suggested avenues of investigation was changing the solution platform from "Any CPU" to x86.On attempting to do this, Visual Studio seems to stop being able to connect the partial classes constructed by XAML objects, with objects declaring that they have no "InitializeComponent" methods, and then failing on down the line until I reach the maximum number of errors.
Oddly, changing the solution platform, and then rebuilding in Expression Blend compiles just fine. Changing the platform back to AnyCPU makes the problem disappear. All projects have compile and debug configurations set to Active. I can't see any reason why simply changing the targeted platform would stop the XAML from generating partial classes Okay, it seems to be that there are some external DLLs to the project, and that those are the cause of what I'd call the first-level compilation failure, as they don't seem to contain any classes once the target platform has switched.In VS2008, this causes the cascading failure of absolutely nothing working at all, as described above, but at one point I somehow managed to import the project to VS2010 with only those errors in place (missing classes, etc.), without the rest of the project imploding.I'm now working on reconstructing those classes from those DLLs, and hopefully will be able to get together a project that will compile on multiple target platforms by the end of the day.
I am generating an array of random numbers for for a class project (simple yahtzee game)I am comparing the output of the array and displaying a picture of each matching dice in a picture box.I would like to use check boxes to select a position of the array so it cannot be changed until the check boxes are clearedWhen the check box is checked, the value of the position in the array should not change.

I am writing a program that will stop the download prompt in the IE control. I have an program that has a browser. I want to fix the browser that way it would stop the download prompt from showing, and stop automatic/manual downloads. I already tried a list of file extensions, then check the URL of the browser for the file extension.
I have a dialog that gets called from time to time. It is only created once, and then shown or hidden. Depending on the current conditions, when I display it, I need to disable the controls on it so that the user does not make any changes.I have code that checks the condition and sets the enabled property to false for the controls. There is a DataGridView control on the dialog, and for some reason, it stays enabled and allows changes. Does anyone know why, or what I need to do to get it to not accept any input?

View 3 RepliesI am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.

View 3 RepliesI have been googling for hours and trying to figure this out, and I just can't.I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly apparent especially on pages like forums or craigslist.
View 6 RepliesI creating a dice game with VB 2008 and am having some problems with control features.When the game starts I'd like the controls to be disable until the user formally selects a NewGameButton.Also, during the game the user gets 3 chances to roll the dice before they select a check box for the type of score they want. They cans select a score at any time during the 3 rolls.

View 2 RepliesI had a form (says form A)with control on it, 2 buttons with text "View Process Flow"(Button1) and "Manual trigger Process"(Button2). Both button will load and shows Form A in Panel1 in Form1, but button1 will let user to see the action but block them on clicking on it, button2 will let User see and clickon the control.
In other software, I can use a transparency button or form block User by acess formA(so, they can see,but not click), But VB2008 transparentcy option kind of idiot(Or i dont know how to use it?)seem it just change the control back color to parent's backcolor(totaly useless, and the "tranparen key" as well)
I cant disable control cause it will stop the animation, only ways i can think off is add in a IF statement in every button, so it will do nothing when viewing = true.
I have my numeric up and down control set up but there is one problem. When i run the application, there is an IBeam in the value box.

I have tried the read only setting but the beam is still there.
