New Winform App With Local Database
Feb 26, 2009I have some scripting exp in html, bash, sql, and am working my way through a video tutorial of VB, studio2008 and access 2008 are the apps, though I am thinking of switching to a freel sql application, as my sql skills are pretty decent, just need to rap them into VB.I am working on creating a winform application that will live on an employee's local laptop, that can be used for tracking troubleshooting incidents. The app will write data to local database first independent of internet connection, but can then upload changes to case data that have taken place since last sync, to the current web addressed server. Presently, we access case data through browser, but it is slow, and very tedious, and my idea is to create a stand alone app that can hopefully automate a lot of the tedious functions.. ie create cases from templates, etc..
So far, I created a layout that I thought would work well, by dragging and dropping from tool bar in Visual studio. I also created a database that can store data locally in access. Now, I am trying to figure out how to bind text boxes, month calendars, etc to the actual fields in the database. I am here for general advice, but specifically, I have a tab with a month calendar tool, and a data-grid view beneath it. I want the user, to be able to select dates, or date spreads on the calendar and have cases relative to those dates, display in the datagridview below.[code]and have the month calendar utility populate the case_dttm portion of the query.

C# - Get The GUI Thread Of Winform?
Feb 1, 2011I have a winforms app with multiple GUI threads. I want them to be able to access each other's thread objects without having to keep track of that information separately.Is there a function in .NET that I can feed a winforms control or window object, and get back the thread? Or a function in the API I can pinvoke for the threadID?
Edit For those of you who for some reason believed my italicized text, congratualations, you're hired!! Here is the problem: "App is crashing in the wild by locking up totally, that is, it stop responding. Very intermittent, and trying to debug it, it seems to never happen."
So what do do? Install an option in the program that the user can activate under our direction, whereby from another GUI thread in the same app, do a thread.abort on the main GUI thread, then we can look at the call stack in the error log. Viola, found an impossible to debug error in less than a day. (Stop now, it had nothing to do with abusing multithreading:-)
I'll admit I almost didn't ask this, the reason I did was I could see an object reference to the main form, but there wasn't any for its thread. I'm giving Chris Shain the answer a/c it is a quick way, unfortunately when the thread is hanging, I wouldn't be able to do an invoke (it would hang too). A little more digging revealed the GetWindowThreadProcessId API call. But it's an unmanaged thread ID, apparently there are complications turning that into a managed thread ID.
So I bit the bullet and put in a global reference to the main UI thread. Would have posted it to begin with, but hadn't written it yet.In main public module/static class:
Public GUIThread As Threading.Thread
Sub Main()

View 2 RepliesLaunch A .wsf From Winform?
Sep 4, 2011ok so i dynamically create a wsf for running an automated telnet session that works great!!(finally!!) but auto executing the script from my code is proving difficult for whatever reason.
I have tried:
Shell("C:shutoffscript.wsf") this produces this result.
also tried setting a bat file that launches the script and launching it as well using shell every time I launch it I get an error in the script that works just fine executed outside my code.
using outfile As New StreamWriter("c:" & "shutoffscript.wsf")
outfile.Write(sb.ToString())
End Using
MsgBox("Script built press ok to execute")
Shell("C:shutoffscript.wsf")
I think this has to be some sort of permissions error right? Since both errors tend to not be able to find the file. Just not sure how to fix it.

View 1 Replies.NET WinForm Memory Consumption?
Apr 19, 2011I've been profiling a WinForm's application using ".NET Memory Profiler".I can't quite seem to understand how my application is growing to 1GB, then 2GB, then 3GB of usage - according to windows task manager.
The private bytes using that tool, and "Total Bytes in All Heaps" shows only as 70MB or so. At the top of my list of instances hanging around, they are mostly String, or WeakReferences to lots of little objects.
All the application is doing is showing a form that loads data from a database. I repeat the show/dispose cycle of the form about 100 times and the growth is continuous.I've tried about 3 memory profiling tools now and none of them are showing me where this enormous amount of memory consumption is coming from.

Sep 25, 2009The application is written using VB in VS 2008 with .NET 3.5 I have a table in SQL Server that represents Invoices and in the table is a field named "Paid" which is define as CHAR 1 with values of "Y" or "N". Nulls are not allowed.I have two Bound Windows forms to manage the Invoice data, one with a DataGridView and the other a Detail Form. Both use the CheckBox control for the Paid field.
In the DataGridView I can define values for the TrueValue and FalseValue and the Database is updated correctly.I can not find anything like this for the CheckBox control on the detail form.Am I missing something? It seems like if it is one it would be in the other for the same control.handle a CheckBox on a Detail form? CheckedChanged?, NewClass for the CheckBox (which I have not done before)? Other?

for x = 1 to 30
picturebox(x).image = value from database
label(x).caption = value from database
next x
Is there something similar i can do in vb.net. I search a lot but found only complex programs difficult to understand and too much of OOP.
