Program 2010 Constantly Crashing
Jan 12, 2012
This is an annoying issue that started less than a week ago and couldn't come at a worse time, as I have a major project deadline to meet. At least once every TEN minutes, the program crashes with the error "Microsoft Visual Studio has stopped working" -- it only occurs when I am writing/editing code while execution is paused (Edit and Continue), which I do all the time since I am stepping through rather complex subroutines line-by-line. I literally have trained myself to save after each line of code I write, delete, or change, so thankfully I never lose much, if anything, when I restart, but it is irritating and time-consuming having to set up everything in the program and get to the place in the code that I was before. I have installed VS 2010 SP1, tried deleting the .suo file, and a few other supposed fixes that I came across online, to no avail.[code]...

for our culminating activity we must make a program that uses a bunch of things etc.
i decided to go the extra mile and make sudoku.
The problem lies in generating the puzzle, the program always crashes, but there is never an error. im sure there are easy ways to make the generator, but from what we've learned this is the only way i know how to do it.
Private Sub FirstBlock()
Randomize()
intNumber(0, 0) = Int(9 * Rnd() + 1)
[Code]....
i made a function for each 3x3 square, and what happens is the block its currently on, checks for interferences horizontally, vertically, and within each 3x3 square, because computers process in order, i set it so that it only checks for previous block interferences, since this is the first 3x3 quadrant, there are no previous horizontal/verticals to check.
The code works fine, the problem is when i run it, it says its running but no form appears, i learned to use a progressbar to try and separate each 3x3 block to generate individually, to try and split the processes up 1 second at a time. the problem is, it does run, but it only generates a certain amount before it crashes, and every time its different, sometimes it generates half the puzzle, sometimes 1/3rd, sometimes only the first quadrant.

In a program I have written I have FileSystemWatcher pointed two directories. When there is a change it keys up and using a listbox rewrites the files in the folder to the listbox. This all works just dandy.. however..
I wanted to change the listbox out for a TreeView. When I first initialize the TreeView on program start, no problems, but when the FileSystemWatcher kicks in the program crashes. I have tried running the debug but it crashes without any error, just the windows error that the program has stopped working.
I am running Dual XEON Quads with 8Gb RAM and Win7 Pro up to date on all patches so there shouldn't be a problem there.
Here is the code for the listbox:
'Setup Filewatcher for Scan Folder List
Public scanfolder1 As FileSystemWatcher
Public scanfolder2 As FileSystemWatcher

well until a few day ago. I don't know what I have introduced to cause the problem but now, whenever I load the project, VS 2010 (SP1) crahes. If I delete the project's suo file, the project loads (really quickly) and all is well until I exitVS 2010. When I re-run it and try to load the project, it crashes again unless I delete the suo file.The program can be built for x64 and x86. Now, when I reload the project (after deleting the suo file), it comes up in Debug - Any CPU mode. I can change from Debug to Release and from Any CPU to x86 but if I try and change from x86 to x64, VS 2010 crashes.This is not always the case though. If I build the x86 version and then switch to x64, all is well and I can build the x64 version. Obviously, there's something wonky going on.

working on an application which performs a set of operations on Active Directory based on an op code.The application was developed long back and has been working fine. I recently made few changes, which is causing the Server to run out of memory whenever the program is being run. I also modified the code to make sure that the variables being declared in each function are set to "Nothing" at the end of function so that the memory can be collected by garbage collector. To make sure, I'm also forcing garbage collection to take place at different parts of the program. But, I still continue to have the issue. The program is very big and hence I could not upload it.
The code retrieves a list of rows from a table with opcodes in it and based on operation code, it performs a set of tasks. The problem is that when it loops through each row in the table, the size of memory required by the program keeps increasing (> 1 GB) to the point where the Server (Windows 2003) is crashing. I have tried different profiling tools, but none of them have been able to detect any memory leaks in the program. I'm guessing that the resources are being held up and hence causing this issue.

I'm getting a really strange error. I have a program that needs to run a thread on startup, and for some reason when I do myThread.Start() in Form1() it will crash with "program is not working" (But only on Windows Server, not on my local machine!). However, if I put the same code under button1_Start() it works no problem. What gives?
EDIT A little extra information: In my thread I have a line of code that uses invoke
Invoke(new Action(() => richTextBox1.AppendText(string.Format("Updating {0}..
", DateTime.Now))));
And for some reason the crashing goes away after I make the thread sleep for 2 seconds before it starts executing. Am I using the right method to execute code on the app startup?

I create a new Windows Forms Application project in VB.NET without changing any of the settings or labels. Then I click on "Add Data Source" and go through the steps in my programming book. Except that Visual Studio is crashing with a message stating that VB encountered a problem...checking for causes...restarting VB.
Sometimes I get to click the "Debug and Run" button before this happens; other times, it occurs before I move all the labels in form from the data source; and still other times, it happens when I click the "Stop Debugging" button.
I have tried removing VB and reinstalling it, but this still is not helping. (If it matters, I'm getting my copy of VB from [URL]
How can I stop Visual Studio from crashing whenever I try to load or work with a Data Source?

This is going to be a strange issue and I don't expect an answer,.I'm using Ghost32.exe to image HDDs within a Windows PE environment. With the release of WinPE 4.0, we can now use the 4.0 .NET framework. So in order to capture any errors that Ghost reports, I'm redirecting the standard error stream so I can review it later.
But, when I implement those two lines of code (highlighted below), the application crashes.I've implemented error logging with the UnhandledException event of the application, but it never fires during this error. All other errors fire, but this one does not.So I ran it in normal Windows and I receive the following error:Quote:The system cannot find the file specified
But when I comment out those lines, it opens just fine. So I'm a little confused.

- I'm working on a windows forms application (.NET 4.0). - My form contains a 'Fast Line' chart using the Microsoft chart control included in VS2010. - The chart gets filled with about 20,000 datapoints. - My application then starts receiving market data from a server via DDE (Dynamic Data Exchange) in real-time and adds it the chart.
Note: I have no control over the server and so I have to deal with DDE only even though it's an outdated technology. VS doesn't support DDE anymore and so I use the Ndde library which works like a charm.
Private Sub StartDDE()
'first we connect to the DDE server:
Dim client As DdeClient = New DdeClient("ServerApplication", "Bid")

I have created several small applications that use my own DLL. The problem is, this DLL is constantly changing. My current solution to this problem is that I have a Setup project in the class library solution that creates and registers the DLL. In all my applications I then have to open the solution and re-reference the newly created/registered DLL. Then I have to re-compile their setup projects, uninstall the old applications, and then re-install the new application.
There has to be a better way and I'm just not sure because I'm fairly new to all this. I have looked into ClickOnce but I don't think that will solve my issue as I cannot publish a class library. I have looked into checking version numbers but I must be doing something wrong because it doesn't work either.I understand that once a DLL is created and being used in an application it should essentially not be touched. I do not have that option in this situation. It is constantly updated. Done.
Edit: The DLL is not constantly changing during runtime but it is constantly evolving to allow more functionality and detail within the other applications. Also, one big thing I guess I should have mentioned is the Public interface is constantly chaning - usually adding new methods.

I am working on a project that reads in data from a device. I am able to read in the constantly changing data only, i need to be able to read in the saved data that is in the device as well.
My question is if the data that is saved in a certain type and i only read try to read it in as text for example, will the saved data I am looking for not be displayed?
ex: im trying to read in text but my device has the data saved in hex, do i see anything or nothing?
idk if this helps or matters but the rs-232 connection is a null modem and im working with VB 2010

I have built a web browser and my new window function is working great, it allows me to open popups that use normal https links without a hassle. But I am having some problems when the links contain java code (like the one below:
("javascript:var%20x=window.open('https://auth.det.nsw.edu.au/pls/orasso/orasso.wwsso_app_admin.fapp_process_login?p_app_id=F0CB644DAE48EDE00D83EFE378FD435E','My_Staff_Email','menu=no,toolbar=no,resizable=yes,scrollbars=yes,status=yes')"
The reason why this operation fails because the string that is being passed to the Navigate method is not an actual URL.It is apiece of Javascript code which needs Javascript engine to process it firstly. Apparently, Webbrowser.Navigate() does not have this functionality,so it fails. If you simply put the string in IE�s address bar and press enter, IE will also not able to open it. The reason why it does work if you access the HTML page in IE and click the hype link is because this will make IE to use Javascript engine to process the code.
Since the API(Webbrowser.Navigate) does not have the functionality to process Javascript code,build up my own code to process the string which you get by using the GetAttribute method. The code reads the string and finds the actual URL and passes it to the Navigate method.
The only problem is that the javascript code constantly changes (varies upon what link is opening) and the url itself will change depending on what the link is linking to! Below is the code that I use at the moment to get the full link .finding the actual URL in the javascript even with the javascript differing from link to link).
Dim myElement As HtmlElement = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Document.ActiveElement
Dim address As String = myElement.GetAttribute("href")

In my program, I have a condition I need to constantly check for. When my program gives an error, I change a label to a different text, lets say "fail" for now. I'm trying to make a condition where the program constantly checks for the label change to "fail" from the start of the program. I am having trouble trying to get this to work.

I have the following code for a gradient form below. When I step through my code it seems to fire constantly. Does this mean that it fires constantly at run-time? If so, is there a way to stop it from firing constantly

Dim Mybrush As New System.Drawing.Drawing2D.LinearGradientBrush(Me.ClientRectangle, Color.LightSkyBlue, _

I am using creating a server/client style program, and it uses tcp connections.Now, the server is like this, but it will only listen until it has received its one request. My issue lies in the fact that it only listens till it receives the one message, then closes. The bigger issue, though, is the lag, it will not let me interact with the form in any way until it closes the connection. Is there a way to make it "passively" listen, for lack of a better word? I do not want it to take up tons of cpu.

I was getting some slightly unusual behavior when using the mouse wheel for some zooming/scaling work (only vaguely related to the earlier thread, for those who remember it). Frankly, it is likely that I have a bug in some code, but that wasn't quite enough to explain what I was seeing. Therefore, I used a error logging feature in my app to note the delta being passed in each Mouse Wheel event. I then ran the app and gave the wheel one good spin, which was about the maximum that I would normally ever spin the wheel in one steady, continuous motion. I wasn't going slow, I wasn't going fast, and I rotated it about as much as my finger comfortably could in a single roll.[code]I then rolled it back the other way using the same motion, and got 8 events, mostly under 200, but one of them was -331 and the other was -7940.
After a handful of tests, it appears that the wheel event is raised often, which is no surprise, but that the values fluctuate all over the place. With a continuous rotation, or as nearly continuous as I can make it, I can see a series of events with one of them easily being ten times the rest.The problem this presents is that the scaling I am using is not smooth (nor is it standard mathematical scaling, but that's a different story). Each zoom level doubles the size of the objects relative to the previous level, though the distance between them stays the same. I would like to do this by dividing the delta by some factor, and if that is above a threshold, increase the zoom level. That won't work smoothly, in this case. If I make the factor something small enough that I pick up a small rotation, then any larger rotation is likely to include a delta that takes the screen through all zoom levels in a single step. Alternatively, if I make the factor large, then all smaller rotations are simply ignored.One option would be to filter out rotation values below 200 and above 800, or so. I am looking for other alternatives.

"To display the webpage again, Internet Explorer needs to resend the information you've previously submitted.If you were making a purchase, you should click Cancel to avoid a duplicate transaction.

I have a DataTable that's constantly being updated with new data from my database via a timer. That data is eventually reformatted and displayed in a DataGridView control.In an effort to prevent the DataGridView from completely refreshing from re-databinding (thus, clearing out selections, resetting scrollbars, defaulting sorting settings, and making the gridview flash as it reupdates), I'm simply removing old rows from the datagrid that no longer exist in the DataTable, and adding new rows to the datagrid that appear in the DataTable since the last update.
For the sake of simplicity, we'll call DataGridView the LEFT table, and DataTable the RIGHT table I'm looking for a way to go through both tables (LEFT and RIGHT), and remove old rows that are no longer in RIGHT and delete them from LEFT. And look for new items in RIGHT and add them to LEFT. Each table has a column called "RecID" containing a unique id for each entry that can be used for comparison. is there a way to do this all in one loop? What I'm looking for, in pseudo code:
<loop through everything>
if RecID does not exist in LEFT but exists in RIGHT
add new item to LEFT
if RecID does exist in LEFT but does not exist in RIGHT
