i want to create an application for inserting blocks from vb into cad,
i want a form with buttons on, the buttons will have the block names on, when you click
on the buttons the blocks will go into the drawing that is open
because i am new to this i dont no where to start
I just did some analysis by using a global function which is called GetCallingMethod in my case.
Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.
In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.
This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.
I am currently working on a small drawing application and I wanted to know if it was possible to insert a paint application inside a form,like vertically dividing the form into two. On one side you have some literature and on the other side you have the application.This paint application just mimics the same Microsoft paint whereby you have an open and save option
View 2 RepliesI have a normal windows forms application. A button launches a command line application.I need to insert an argument automatically without the keyboard. Then hide the command line application. I've been trying to figure out how to do this but with little success.I need to build a function that does this but I've never built a function before.Here is what I have but it tells me it may result in a null exception.(Because I'm not doing something quite right.)[code]

View 12 RepliesI am working on a project that requires that I use nested case blocks. However, I am not quite sure what this looks like. And for whatever reason I'm having a hell of a time trying to find the answer through google. Are nested case blocks like nested if blocks? Or are they something completely different? More information on the project can be given if needed.

So you know how when you call "Form.ShowDialog" from where ever you call it, it blocks until the form being displayed closes. And then the function returns whatever result it was.I want to know how to block like, but without a form, yet still have the "main ui thread".Basically I have this long process that needs to thread out and do several things... and it's heavily event based. It jumps between two threads, the main ui thread, and it's own background thread. The main ui thread needs to have access so that I can randomly open different dialog boxes for things... sometimes they're just windows asking to hit OK or Cancel to continue, others it's to perform some action, etc etc.
But there is NO central form related to it. It's a complete background thread running that randomly hops over to the main ui thread for things.Right now I have this class I designed called lets say "DoJobProcessor". On it is a function called "BeginDoJob" that threads off from the thread pool... when ever I need to jump back I use a ManualResetEvent to block on the background thread, jump over to to the main thread with "invoke" and passing a reference to the MRE, then release the block when done there and continue on on this background thread.
All while this is going on I just set the form I'm trying to block the main ui thread from managing by just setting its Enabled property false.It all feels just messy and annoying... and I was just writing something using ShowDialog and I was like... HEY, what if I could block this BeginDoJob method, hi-jack the main ui thread, then let that function return the result when done instead of having this "Complete" event with the return value in it. It's obviously possible because ShowDialog does it, but I don't know how.
This way the job I'm performing isn't always waiting for the main ui thread, instead its the other way around... the ui thread waiting for it, the way it aught to be. Show something, branch off do some stuff and just idle the display while it does it, come back show something else, branch off and just idle while it does that.
Im working on a somewhat major program for my work. Just in short, im reading in a text file but i then want it to break the text file into blocks. I will put a quick snip of it here:

So i figured id see what the pros could tell me. I have a couple good links, one for a regex cheat sheet but i just dont have a very good understanding of regex.
What is the convention in VB when a sub requires that a try/catch block succeed in order to function, but the catch block doesn't bubble the exception up?
I could put all of the code into the try block, but this seems messy since most of it doesn't need to be tried, it just needs the try to have succeeded.
For example, should the catch block exit the sub? This would work in my current situation, and if it is the proper procedure, let me know, but what about the more general scenario where both both success and failure require additional processing?
I am using a WebBrowser to load a webpage. In that page, there are several links. When clicking on one, it opens and then immediately closes. IE7's popup blocker is set to allow all from this site, nor does it work even if the popup blocker is completely disabled. I have no other blocker running.
how I can make these windows stay open?

I think about CASE, but not very sure,
So if dropdown list.selectedvalue=sheet1 then

While running an application in the IDE, the program properly handles Try/Catch/End Try blocks. This works fine for the most part, but is it possible to have errors generated in these blocks stop execution at the line with an error on encountering an error?

Following is the code that I'm using for reading data over a .NET socket. This piece of code is run by a single separate thread. It works OK the first time, on the second iteration it stops at "client.Receive(buffer)" and never recovers from it. Initially I was using recursion to read data but changed it to iteration thinking that recursion could be the source of problem. But apparently it is not.

Using Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text
