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.

I have a main(frmmenu.vb) form which is the mdi parent of other two forms (namely frmcandidatelist.vb and frmviewcandidate.vb)...........Two forms are displayed simultaneously on frmmenu each separated by split-container(frm-candidate-list.vb on left side and frm-view-candidate.vb on right side)
Frm-candidate-list.vb shows name-list of customers on a datagridview. While i click on a item from that list, details of the respective customers(like name,id,photo,address,etc) is displayed on the right side form(frm-view-candidate.vb).....
But there is a problem. Loading details of a customer takes time(since i have to connect from remote database)... So the whole program becomes hanged(like) till details are loaded.....

Should I uncheck some options?
View 6 RepliesI am creating a server-client type application that allows the network administrator to perform tasks on remote computers by using TCP sockets (TCPClient and TCPListener).The server application needs to send out a message to a client machine (with client application installed) and from this, the client application will send back the required data (i.e. system info, task progress etc). This part works fine.However, I am having trouble in getting the client application to constantly listen for an information request in the background. It should be listening whenever the application is running. What I want to do is to have an event handler which, when a message comes through, acts upon the instructions to send the relevant information back. The server does not need to constantly listen for data, as it will only receive data after it has sent a request.

I like to make an console application to measure the time it takes to fully load a web page, what's the best approach to do that? The purpose of this small app is to monitor some pages in a website, in a predetermined interval, in order to be able to know beforehand if something is going wrong with the webserver or the database server. It would be nice to be able to measure the time it takes to fully load the the page (images, css, javascript, etc). I have some code but I is not measuring the fully page.
Dim sw As New System.Diagnostics.Stopwatch
Dim req As System.Net.HttpWebRequest = CType(HttpWebRequest.Create("[URL]"), HttpWebRequest)
sw.Start()
Dim res As System.Net.HttpWebResponse = CType(req.GetResponse(), HttpWebResponse)
sw.Stop()
Dim timeToLoad As TimeSpan = sw.Elapsed
there is a "open with" option in the context menu right.if i select the application(app i have build from VB2010) from the open with option. i want the picturebox in my application to load the image i had selected(the one with the "open with" )
