My app pulls news stories from my website and dumps them in a contextmenustrip. If for some reason they can't be gotten, then a refreshbutton appears instead.I'm using this code to perform an action based on the content of a contextmenustrip. But how do 'override' the default to allow for the 'refresh' option? ie - would should I put here -->

I have a TreeView with dynamically added nodes which I am using to actually contain textual data. I am using the tag field to contain special info for acting upon, based upon the node's tag. I have tried using treeview.SelectedNode.Tag. However, the selected node is the one most recently selected (like with a left mouse click), not the node I right-clicked. I have also tried using the contextmenustrip.SourceControl, but the source name for the control is always the container, the treeview control rather than the individual nodes. I have even tried associating my ContextMenuStrip dynamically to each individual node as it is added. The behavior is the same.A workable solution might be to cause a left-click when I do the right-click to bring up the context menu strip. I haven't been able to figure that one out yet either.

I'm using VS2010, SQL2008 and using asp.net vb - im stuggling with some db related items.I have a couple tables, Project and Projectstatus - looking something like this.project
- ProjectID (autoincrement)
- ProjectName varchar50
- Projectoverview varchar200
Projectstatus
- statusID (autoincrement)
- projectID varchar50
- projectstatus varchar200
What id like to happen is that when i create a new project (into the project table),that a row is created in the projectstatus table, inserting the projectID from the project status for reference.I don't think this can be done from within VS, correct? therefore, do i need to create a SP to perform this action from DB side?
I'm using ASP.NET/VB.NET to create this with SQL 2005. I have a project where I'd like to take a set of records from a table, then send each one through an API, get a result and writeback the result to a table, then move to the next.
Initially, my thought was create a SQLDataSource that grabs all the records, then perform the action on a button to do the action of sending through each record.
Is there a way I can call the recordset from SQLDataSource and perform a loop? I'm thinking something like in Classic ASP/VBScript where you would open a RecordSet, do an action, then Loop until the RS was EoF.

View 1 RepliesI have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.
can i detect if a text box is showing 15 and descending and then perform an action?

I'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.
View 2 RepliesSay you wanted to set a status message
' Set status
ssMainMessages.Text = msgValidating
Then perform an action that requires a http request that takes around 5 seconds then you want to display the result of that
' Set status

It will only always display the second message? Its like it jumps the first part of the code and goes straight to httprequest.even if you put the update,system,threading.thread.sleep ....

I'm making a new design for my website, but I want to keep the old one and possibly switch between the two.
Unfortunately, I've changed the content on the Master Page (luckily I have a backup).What I was thinking was to keep separate master files for each theme, and then just determine which one to server based on which stylesheet is loaded.
The only way I can think to do this is to keep a "settings" file on the website that has a "stylesheet=1/2/3/4/etc" line. Depending on the number there, the server will serve the correct master page.
Alternatively it might be easier to do something similar, but instead of serving a whole different master page, set a specific stylesheet to use.In both cases, I need a little help with actually doing the work on the server. I can read a text file (even encrypt/decrypt a file before and after it gets read for security), but actually giving the server the instructions based on what is read is where I'm lost.
I've been trying to figure out the easiest way to populate a menu to allow for easy updating in the future. I would like to add anything to a specific folder and when the program runs it would be populated by the contents of the specific folder. Is this possible? What should I look into to do this? Not sure of the process to use to do this, that is if it is even possible.

I've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.

So I have a bit of a problem and maybe I'm going about it in the wrong way UNPOSSIBLE! :-D
All I'm looking to do is create a few popup menus using contextmenustrips, it seems reasonable enough to me. What I want to happen is when I mouse over a label I want it to open up the contextmenu and THEN close once I am off the label and the contextmenu strip WITHOUT having to click the form. so I can go up and down a set of labels and popup menus as I move the mouse over each. This has turned out to be much harder than I anticipated. :-o
So at first I though ok lets try this code below. But this just causes the menu to flicker I "thought" focus would go to the contextmenustrip but i doesnt seem that way
Public Class Form1
Private Sub Label1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles label1.MouseHover
ContextMenuStrip1.Show(Label1, 20, 0)
End Sub
Private Sub Label1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.MouseLeave
ContextMenuStrip1.Visible = False
End Sub
Private Sub Label2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label2.MouseHover
ContextMenuStrip2.Show(Label2, 20, 0)
End Sub
Private Sub Label2_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label2.MouseLeave
ContextMenuStrip2.Visible = False
End Sub
End Class
So then I thought ok well I'll just try to have it where when I leave the contextmenustrip I'll close that. THIS WORKS but not exactly how I want it to I can hit a label then jump onto the menu then off to another label but cant go label to label up and down the form.
Private Sub ContextMenuStrip1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ContextMenuStrip1.MouseLeave
ContextMenuStrip1.Close()
End Sub
Then I thought ok well how about something like
Private Sub Label1_MouseHover(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.MouseHover
If Label1.Focus Then
ContextMenuStrip1.Show(Label1, 20, 0)
Else
ContextMenuStrip1.Close()
End If
End Sub
But that didnt work either, I have another vb.net guy with me and hes all *shrug* I'm probably just going about this in the wrong way your suggestions are welcome. Thanks mucho everybody
