View 1 Replieswinforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

View 8 RepliesI am trying to build a class that works with a form, but I keep getting the dreaded "Object reference not set to an instance of an object" Error.The form basically collects test grades and assigns them to a collection.My class code is as follows:
Public Class Scores

Public mintSum As Integer
Public mdecAverage As Decimal
Public mintMinimum As Integer

I had a similar project I was working on that had a collection in it, but now that one is giving me the same error. It there something with my version of Visual Studio that is causing this error possibly?

I've have found answers here frequently in the past just from browsing. But now I'm completely dumbfounded.
I'm using Visual Basic 2010 Express, on Win7 32bit. My application talks to an Arduino via a virtual com port provided by a cheap Bluetooth to serial adapter. I use a text based protocol that is working fairly well. BUT one method in my code, taht seems functionally equivvalent to the other methods is locking up my whole window.
It does this whether I'm debugging or running the exe.Below are the offending method, and a simmilar one defined above it that works with no problems.
[Code]...
If I comment out the cal to write, everything works fine. Aside from me setting some state bools and playing with button titles in the first method, I can't see the difference as to why one works fine and the other hangs.
I really hope someone has some experience in the SerialPort object and VB that can shed some light on this.I've tried everything I can think of. I thought maybe it was the inline concatenation, so I dim'd a local and assigned the string to it, and passed that to Write. But I have another method that uses inline concatenation that doesn't do this.
I have created a calendar in VB which works fine when set to the startup form, but when I use the MdiParent form as the startup form and try to display the calendar by use of a control it just shows all the buttons and labels with no values assigned to them. Its almost as if the Calendar_Load event is not working, or not accessing the methods in my CalendarClass.
View 2 RepliesI am running a website for a F1 racing game, where users can submit their laptimes and compete with each other for the fastest time.
I am now trying to have my website create an image of the top-5 users every... 5 minutes or something, and copy it to the webserver somewhere I can link to. This way the image under that link will update with the latest information every 5 minutes.
To layout the times (these also include the position (1 to 5), the username, the platform, the time of course, and some more details) I am using a DataGridView. I could take the long route and layout the specific 'columns' manually, but I thought using a grid was far easier. I simply set some properties of the grid to make it look nothing like a grid (basically hide the column and row headers and grid lines and give everything the same backcolor). Then I load the times into the grid, and take an image of it using the Control.DrawToBitmap method.
This works fine, but it returns the entire grid. This is a problem because I made the grid extremely large (5000x5000) so that it can always accommodate the times regardless of the length of the usernames. So, the image I get is 5000 pixels wide while it only contains data in the first 500 px orso.
I am currently using the GetRowDisplayRectangle and GetColumnDisplayRectangle methods to figure out the part of the grid that actually displays the times, and use that to cut the image down to the portion I need.
But here's a problem: these methods only return something when the grid is on a form that is currently being shown! I am already giving the grid a parent form (even though I am just creating it in memory and it doesn't need to be displayed anywhere) because otherwise the data wouldn't load, but I was never showing that form. Now it turns out I do need to show the form, very briefly, in order to figure out the area that I need to take a snapshot from.
Remember that this is all happening on a webserver, so I'm not absolutely sure if this is a problem. Is it ok for a webserver to have a form popping up and down every 5 minutes? Or will this cause problems? I honestly don't know but I don't think it's a good thing. Moreover, it also pops up on my own machine when I'm testing, and it's damn annoying.
So my question is basically twofold:
1. Maybe I should ask this in the ASP.NET forum, but is it a problem to show a form briefly every 5 minutes?
2. Is there any other way to get these Get...DisplayRectangle methods to work without having the grid on a physically visible form?
I am here with the same Query but with a different look I want to apply the culture change to my program. I created a class library for culture change. and applied it . It is only working with the form name, i did it with two different languages and got the result. But the controls inside the form remains as it is.
