View 12 RepliesI am starting a Console (3rd party application) with a New Process in vb.net. I simply want to size the window when it loads. All the APIs have not worked, SetWindowPos, MoveWindow, etc... need to work in all versions of Windows. Anybody have solid code that does this?
View 4 RepliesI was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

I have a console application I'm using to run scheduled jobs through windows scheduler. All the communication to/from the application is in email, event logging, database logs. Is there any way I can suppress the console window from coming up?

I am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.

View 2 RepliesI am trying to send/print/write all possible ASCII codes (0-255) to another console-window application. From my application I would enter the name of the "receiving" application and the comma seperated hex values that should be sent/print/written to it. I have used AppActivate to select the "receiving" application and then have used sendInput and send.sendkeys to attempt to send the desired ASCII value. However, these appear to have limitations on values greater than 127. I need to be able to send all 255 values.
View 1 RepliesHow do I get the console from closing immediatley upon opening in a Console Application program? I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.
View 7 RepliesIt sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?
Within the program, there is a button that opens a file inside of a second form ( DocViewFrm ) and it works fine the first time around. Within this new window, there is a button that uses Me.Close() to close the window and return to the main window. Upon the attempt to open this second form a second time, the program crashes on the Me.DocViewFrm.Show() line. The error message reads:
An unhandled exception of type 'System.ObjectDisposedException' occurred in System.Windows.Forms.dll
Additional information: Cannot access a disposed object.

I put a shockwave loader into my VB.Net application. When the shockwave loads, it opens about 20 different IE windows and says page cannot be found, while correctly loading the shockwave movie into the application. It's bizarre... how do I fix this? Not even sure if I should post this in this forum or a flash forum.

My application is runs without any external dependencies like .dlls. When I run my app, the controls flicker on as it loads. It's not terrible, but it's annoying and kind of takes down from the professionalism. I was trying to figure out what was causing it and found out that it was my background image. My background image is a jpeg and I guess it is too large. Is there a way I can get it to load the image better so my controls don't flicker or maybe use a different file type that is smaller?

View 3 RepliesSo in this program that I've made, I have 5 tabs. One of them uses this chart control for .NET ver 3.5 that I downloaded from the Microsoft website. The issue is, though, that when I start the program, everything is fine until I click on the tab with the 3 charts on it. The tab freezes a little bit, and it takes a few seconds to load the charts. After this initial hiccup everything is fine, but I've tested this on three computers now and it happens to all of them. Anyone know what I can do to make these charts load faster or smoother? This is quite a roadblock.because otherwise I'd be done I've been working on this project in VB.NET for the past 3 weeks and it's my first time using the language.

I wrote this application in VB2008 and it ran for three years without problems(It had one first chance error during that time but ran correctly). I started having problems at the first of this year with a textbox not showing the update for the date code correctly. So I thought that maybe some update to the system had changed and I might need to do some code changes to take into account for these updates.I first tried to convert it to 2010 but the conversion would not operate correctly even though the code showed to be correct.It would jump from one form to another in the middle of a if statement using debug to step through the code. the if statement would just test for a variable to be less than 2 and then be changing the text in a textbox. So I decided that It would take longer to correct the converted application then to just use VB2008.
So I went back to VB2008 and my XP to find out why the date code had quit working. This code had been working correctly for three years.I was thinking some of the code used had become outdated in some way, because a copy of the original source would not run in debug mode correctly. It showed the same problem of not updating the textbox. I stepped through debug and found that it was doing the same thing as the VB2010 version and jumping in the middle of the if statment. So I rewrote the code and used the format string command to build the date code in stead of the seerating out the date into 3 variables using a split statment.This works for the textbox problem and stoped the jumping to a different form. But since I have went back to the original code I have the first chance errors comming up.
I have several first chance exceptions being thrown from debug. This happens when I fisrt start the debug and I have put break points all through the applicatins to try and find the problem I have also enabled debug exceptions Common runtime thrown and it still gives the exceptions but no break point.I have option Strict on. There is no errors or warnings showing after a build. I have cleaned the solution and exausted all my methods of troubleshoooting this problem.The following is what I am recieving while in debug mode in the immediate window.
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe

A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Now if I run this as a published application I get the same error as the first one on the above list and it gives a error window with continue, exit,and details, if continue is pressed it will allow me to continue and the application runs correctly.The details just say basicly the same as the error with no error number and that the error was in my application.exe. Nethier of these errors will give a break point so that I can find the problem. The problem does not appear to be in my code because this happens before the first form appears.
I have a vb.net project in vs2008. When the project loads, one form is always immediately marked as changed before anything has been done to it. This didn't happen in earlier versions of the form. Nor does it happen with any other forms, classes, modules, etc. I have no idea why it is occurring but I am curious.

I am trying to do repetitive loads of images to one picture box. That is: An image is loaded to the picture box from a bitmap image.It is done this way so the image can be scrolled using the mouse.That works fine.The image is loaded from a file.When I attempt to load a second image from a file, I get an error indicating that the resource has not been released.I have tried Dispose() etc, nothing seems to be working.I started with VB 1.0 and worked up through VB6 over the years and am now transitioning to VS 2010. A bit of a neck snapper, but it seems to be worth it.
