One of the features of the application I am working for is that it needs to check if an external windows application..lets call it A, is running. If it isn't running, then start it. If it is, then leave it.My idea originally was to use the process name as a filter. But the problem is that the process for application A is javaw.exe. Application A, belongs to a toolset, which has other windows applications, which have the same process name, javaw.exe.I already know that one of windows which has a javaw.exe process has "Edit"..in its title bar. So my algorithm to filter for app A is:
1. GetAllExistingOpenWindows
2. For each window in AllExistingOpenWindows
3. if window.processname=="javaw.exe" then
I'm reading a binary file into a bindinglist of (t); to be bound to a datagridview.Each line in the file represents a single transaction but I need to consolidate and or filter transactions that meet certain criteriaI know how to do this from a mechanical standpoint (looping the list while adding each item, and adding a new item, or merging the data with an existing item), but I'm looking for a practice, pattern, existing components, or something else that I'm missing (I'm drawing a blank for keywords to search).I don't want to reinvent the wheel if I don't have too. I'm particularly concerned with speed and performance issues with 100k plus records to process in some instances.Currently working with .NET 2.0, but will move to 3.5 if a particularly sexy solution exists.
just wondering if it is possible to add a method to all forms in my project without having to do it on one form and Inherit all my other forms from that one

im using vb.net winform.i want to update a datatable to sqlserver. but before that. i need to check by comparing it to another datatable(same structure but contain new data). i need to insert new data only.
I am editing an application that was developed using VB .NET. The form has a button, I see it in the code but it is not visible in the Form. Also, when I place a new button, it comes as Button2 meaning there is a Button1 - I am not sure how to find where it is and place it at the right place.
I'm trying to add a DataGridView to a Split Container Panel. I am able to add the control, but it just places it on top of the old one. What I want is to add it below the existing one. How to do it.
Not sure what I am doing wrong here but I have 2 buttons and a rich text box. The issue is when I click the second button to add text to the rich text box and it over writes the current text that is already in the rich text box. How can I code this second button so that the text is added to the rich text box and not replacing the current text?
Here's my Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click RichTextBox1.Text = "This is the first line" [Code] .....
Also how can I add spaces in a line of text (or in the middle of a sentence) so that I can insert a variable in the line. Example: "This is the" variable1 "line of text" "This is the" variable2 "line of text"
I have the code which checks if there is a selected tab
Private Function GetBrowser() As WebBrowser If TabControl1.SelectedTab IsNot Nothing Then For Each c As Control In TabControl1.SelectedTab.Controls If TypeOf (c) Is WebBrowser Then Return c
I want to use automated testing using autoit for my existing windows form based application. Currently looking at the autoit documentation I couldnt figure out how to start a existing windows application in vb.net and then use it for further automation.
I have a Visual Basic .Net form (launches after the splash screen tests database connectivity) and it is not focusing above other existing windows on launch. How do I get it to focus above all existing windows and Windows Explorer windows?
I need to create a timer that sets the time from an existing text file. The time format in the text file is 00:00:00 (hours,minutes, seconds). An excerpt from one of my text files looks like ClockSet = "00:49:05"
Also, if possible, when the timer reaches 2 minutes I would like the backcolor to flash between red and green.
I have a panel with some controls in it (several textboxes, a slider, 2 buttons, and a small groupbox).. When I click a button, I want all of the textboxes within the panel to be readonly... So I have this code: [code] When I run it though, I get the following error:Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.TextBox'.If I remove a button, it moves on to give me the same error but for a label..
I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.
.NET developing and have a simple question, i've been stuck on this for a while and searched many forums first with no solution so i'm posting myself. In VB for excel i've used Screenupdating=false to disable the screen updating however now i'm creating a visual studio 2010 windows forms application and its not showing up as a property. Here's the code i've tried.
I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I would like to know if its possible to start up a second windows forms inside the parent form. Ex: A button is pressed and a new form is showed. I would like to keep that new form inside the parent form, and have it not be able to go outside the parent form.
I am writing a program for my A-level coursework But for some reason I got this build error this has never occurred to me before, I have no idea why I can't use string for the name of my form.
a program and i need to have a button put a file into a folder, i know how the button works i already have it doing some other stuff. i just don't know the code to copy and past it to a folder.
When I add a new, empty form to my VB.NET VS9 project, the linenherits System.Windows.Forms.Formis missing.What am I doing wrong here?I thought it would be added automatically.I experienced that some thing get weird if this line is not there (Form_Load is not firing, I think).
I've successfully saved video files into SQL server as varbinary. Now, my problem is, how can I play those videos in Windows Media Player (embedded in my Windows Forms).

I am making a System Tray Application when i minimize my form its hide itself in the tray but whenever i click on the tray icon my form shows now when my form shows up i would like to disable my Background desktop same as CardSpace when its shows up.
I have a problem with scroll in a treeview in a Windows forms application (Framework version 3.5).
The strange thing about the problem is that on Windows XP, Windows 7 and Windows 2008 the scroll works as excepted, but in Windows Server 2003 SP2 the scrolling doesn't work. Enable/disable Visual Styles doesn't seem to make a difference on Server 2003.
Steps to reproduce the error:
1. Add a treeview to a form and add x nr of root items (and 1 sub item to each item).
2. Expand a number of nodes. The non-standard thing here is that we are changing the node integral height because we display a usercontrol with the treenode (See example of the code below).
3. When you scroll afterwards, you cannot scroll to the bottom node. The scrollbar is all the way down, but we are not seeing the last node.
Public Shared Sub SetNModeHeight(ByVal Node As TreeNode, ByVal IntegralHeight As Integer) 'Create instance of tvitemex structure.
I was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)
Sub startup_args() If Environment.GetCommandLineArgs.Contains("+game") Then Dim path As Array = Environment.GetCommandLineArgs
[code]....
just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:
If Evnironment.GetCommandLineArgs.Contains("+game") Then Dim path as string = Environment.GetCommandLineArgs.tostring MsgBox(path)
My question is, am I able to share a business logic layer seemlessly between the two presentation layers or is there anything I need to watch out for. I'd really like to not have any duplication of business logic, so any advice would be more than welcome.
I noticed that adding a MenuStrip (from the Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like Visual Studio's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar.Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)
