I have a context menu strip on my application but I would like to associate it when a user right clicks on a list box in my application. The context menu appears on my mouse right click event in my listbox, but it appears at the top of my application instead of where I right clicked. How do I associate the list box control with the contextmenu.
NOTE: Maybe there is another control besides a contextmenu that I want to use here.
I made context menu for UltrawinGrid, when i click right mouse button then the context menu open. This is the code that I use for my menu:
Private Sub ShowContextMenu(ByVal mousePoint As Point) Dim cMenu As ContextMenu = New ContextMenu cMenu.MenuItems.Add("Delete") cMenu.MenuItems.Add("Copy") cMenu.MenuItems.Add("Paste") cMenu.Show(UltraGrid1, mousePoint) End Sub
Now I want when I click on context menu item, for example delete, to call function that gone do something, how i can do this? How I can make connection between menu items and functions?
In Visual Studio 2008 I tried to add xml file as embedded resource. During compilation the embedded resource item was simply ignored and the resource I expected to find in resulting dll was not there. I tried several times with no positive effect. Finally I decided to rename the file, so it does not have xml extension. As soon as I changed the extension to (it was .en in this case) Visual Studio started picking the file up and embedding it as part of the assembly. I could not find any any documentation on that odd behavior. Does anyone know if that is expected, and, if so, why ?
I need to create a list of possible images to change picturebox controls to. I have the images loaded into the My resources folder of the solution, but I need to create an array referencing them. What data type do I use for the array?
When bulk renaming files (14000 of them) i get this error: The CLR has been unable to transition from COM context 0x4cefd8 to COM context 0x4cf148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
My code is as follows:
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim asd As List(Of String) = FileIO.FileSystem.GetFiles("D:Music").ToList Dim rs As New ADODB.RecordSet("SELECT * FROM Songs", My.Settings.Files_Database__Connection)
I have a simple app (coded in VB 2008 Express Edition) that uses an SQL Server database (in .mdf format) that works fine on my own machine. I created the database in SQL Server on this machine. I added the DB as a data source and it works fine. But when packaged this app (ClickOnce) and installed this app on a different machine the installer tries to download MS SQL Server Express. Obviously this is because SQL Server is a prerequisite and is not installed on the other machine. But just as obvious is the fact that the download will take a long time to complete before my code even starts installing.
My question is this: Is there an SQL Server reference (using Add Reference...) that I can add to avoid this? I suspect the application just needs one or two DLL files from SQL Server. Downloading the whole product seems like overkill. Is there a way I can included the needed files in my app to avoid this long download process?
I'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.)
In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File-->New, they can create a new copy of this template, give it a filename, and save it to their local directory.
The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor)
I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime?
I need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.
I got this message because of a long process: ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x3dc190 to COM context 0x3dc300 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time.
To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations. I've poked around on the internet and on a forum, someone suggested to use application.doevents(). I did that and the messaged goes away. In an earlier thread a member wrote that using application.doevents rarely was used appropriately. Is my situation a proper usage of application.doevents or is there something else I should be doing?
I have a resource file that I include in my shared code library that has all of my re-usable classes in it (all the resources go into their own namespace). Now, what is the best practice regarding resources... should I include them in the same DLL, or should I have a seperate resource DLL and/or are there any benefits from seperating them out into their own file.
VB express 2008 .net 3.5 or .net 4.0 VB express 2010?I have written application to convert RTF to HTML. The main Purpose of the application is to copy VS code to the clipboard and covert it then put it back into the clipboard as a HTML Document so that it can be pasted into a HTML document such as Windows Live Mail. I found that code copied and pasted is spaced out in in the wrong positions.
The applications works perfect with no bugs so far. I then asked Myself how to go about doing the copy with the least amount of operator interaction. So I added an Icon to the Icon Tray with a right click menu to use to convert once the Rich Text Format was copied to the clipboard. This works fine except you have Five steps, Select the text, Copy to clipboard, Right Click the icon, Select the Converter and Paste. The normal is three steps.
To this the best solution is to add a context menu item to the active form such as the RTF editor or window. So that when you select the Rich Text to copy and right click on the form to bring up that menu then to Just Select the menu Item such as "Copy RT and Convert" I searched and found about 544000 Items and tried to restrict down to no avail. I read until I finally gave up. I did not find any code examples of this. Almost every thing I found related to the web or some other explicit document like Excel and not to the Various windows that could be active with RT in it.
how do you add a context menu item to the context menu of an active rich text format window such as WordPad or VB?I have test in my application that tests to see if it is a RTF in the clipboard so if it is not the converter does nothing.

So i created resource file New --> new file --> Native Resource Template Then added icons with custom id, like "x", "u_100", .. so i understand, what the files (in my case icons) is.. And i saved as 32-bit resource file (*.res) So i have a question, how can i use these files inside of resource file in my apps? i know how to add icons in to my app.. Me.Icon = New Icon(C:/icon.ico)
Is there another way to add a Context Menu to a ToolStrip other than using the MouseDown Event? I want to use it to let people select to either show text labels on buttons in the ToolStrip or turn them off.
How to put my video player to the context menu? But I also need to know how to make it so that when my video player opens that it will it will load the file that I wanted to open with my video player.
I have a project that I have upgraded from .NET 1.1 to .NET 4.0. The project uses Windows Authentication (internal Intranet webpage). I setup Windows Authentication in IIS 7.5 (running Windows 7) following the steps laid out in this article.[URL]..I can now build the project. I can open the project by opening IE and typing in the URL on localhost. However, if I try to debug the project it throws an NullReferenceException on this line in the Application_AuthenticateRequest in Global.asax.
dt = oDBLookup.GetPIMSUserRoles(Context.User.Identity.Name)If I set a breakpoint there I see that Context.User is Nothing. If I set a breakpoint in the same place on the 1.1 project (different box, running IIS 6) it has my Windows Credentials.Why would Context.User be Nothing ONLY when I am trying to run from the debugger in Visual Studio 2010 Professional, and not when I open the web project directly in IE?
I get this error mssg; Microsoft.Net Framework//An unhandled exception has occurred.Cannot Generate SSPI Context.The SQL Server is on a SERVER and my program is on the client machine.I believe it (Client machine) is loosing its network connection. Because once I re-bot the system it connects fine.I am going to try and PING the SERVER when it comes up next to check the connection.I tried googling this for a resolution but to no avail.Do u think I will have to reload the OS on the client machine or just the Framework.
I have an application that is simply an icon that sits in the system tray, with a context menu that opens upon right-clicking. One of the options in the menu is a text box where the user can enter a number, and press enter to perform a specific action (which is not significant to my question). The problem with this, however, is that if the mouse moves away from the text box, the menu closes.
Is there a way to keep the menu open as long as the text box has focus no matter what?
So what does this mean and how do I fix it? This message occurs if I place the New keyword in the line(s) below. If I remove it, i get an error at runtime saying I need to use New. What am I doing wrong? Code:
I've been upgrading my vb6 app to VB.NET and so far everything was going on smoothly until this morning. I'm getting this message : value cannot be null. parameter name context when trying to save or when adding new controls. It's kind of a random error, it does not always happen when saving or adding new controls
I've attached a context menu to a richtextbox. This textbox contains lines of data, and I want to find the text of the line which the user has pressed.I found how to do it after the user has chosen one of the context menu items. But I can't figure out how to do it before or when the context menu is opened. The reason for that is that I'd like to disable one of the context menu items if the line of text is missing some text. I tried the following but it's not working:
Private Sub ContextMenuStrip1_Opening(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart) Dim line As Integer = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart)
