Develop An Application Which Doesn't Lose It's Focus?
Apr 22, 2012
I want to develop an app which won't allow the user to open or jump to another application while it is open. It should be in Visual Basic. For example, if my application is open (running) and the user tries to open any other windows application like "media player" then it shouldn't open. The app should not even allow "task manager" to run. The application should completely block the windows environment while it is running.

I want to detect if a user has alt-tabbed to an other application, so that I can auto pause my application, or let my application blink in the taskbar. Problem is that I can't figure out when someone has alt tabbed to an other application or has clicked an other application.

i have this form, lets call it form1, i dont want the user to be able to click outside the form or let the form lose focus, kind of like when you are setting an options for a program and you click outside of the options settings and the options dialogue box flashes and refocuses your mouse on it and wont let you click anywhere until after you hit ok. i also dont want the user to do a cntrl + alt+ delete and open that options box thing that takes over your screen

I've got a lose focus textbox which when data in entered and the tab key is hit the code is executed as expected and a message box appears informing the user of the outcome. However when I used a barcode scanner with a tab function embedded, the code is executed and the data is inserted into a database but the textbox to say if the request was successfully completed or not does not show as expected.

I have this rather annoying problem when printing in VB.NET. I use the PrintDocument object and after it has done its job, the form gets minimized to the taskbar. I tried to force the focus on the form but to no avail. I was just wondering if someone else has encountered this problem and maybe has a solution for it?

I have an Unhandled Exception handler that does something like this[code]...
So it looks like from the "add" that the last person that subscribes to Application.ThreadException is the one who gets it (it's not additive as most event handlers are). I don't want to give up my subscription to this eventhandler no matter what. Can anyone think of a way that I could track when I lose my subscription to the Application.ThreadException so I can steal it back from whoever stole it from me?

I have a ToolStrip Control on a MDI Container. The ToolStirip has some ToolStringButtons on it. We are using .NET Framework 2.0 and VB.NET. If the Container doesn't have focus , the toolStripButtons do not recieve click, but if do the same with normal button it happens. how we can make these buttons click even of the form doesn't have focus. I tried fixing it by using Form Activate event and check if the button is selected fire click event.

I am new to this forum and I would like some help from my respected seniors.I am trying to develop a ASP.Net Web Application using C# or VB. First of all prefer me whether C# would be easy or VB for the following scenario:Below are the requirements:
1. For All Users:
Text-chat feature will allow users to chat with the available online users.
2. For Registered User:Allow users to create new folders and sub-folders, to store (upload) files.Allow users to perform move/copy/delete operations on folders and files. The percentage of storage capacity remaining and used should be displayed on the top. Automatic versioning system will record the version/revision information when a file is replaced/overwritten Team management feature will allow users to work in teams (by inviting other existing registered users). The activities of the team include access to the password protected area for the team, uploading files, commenting on the uploaded files (discussion), polls, automatic and manual reminders to the team members.
3. For Administrator:
Approve/Reject new team requests; update/delete existing teams.View all the files and folders uploaded on the server.Allow to perform delete operation on any existing file/folder existing on the server.Delete account for any registered user.Define and Edit storage capacity and other limits such as Maximum file size allowed for uploading.
Queries:
1) As, every user will have his/her own PERSONAL profile page then how will the system redirect the user to his/her PERSONAL profile page after hitting Login?
2) How this chatting feature can be developed?
3) How this storage capacity would be assigned overall?
4) How Administrator will manage all this?
I am totally confused.I have developed SRS as well. but in coding I am totally stuck as I am not so good in coding. I thought Visual Studio 2010 would help me effectively in this case, and I am trying but couldn't find any way for this to be done.

I am very keen to build a simple application to convert AVI to jpg in order to learm a little about video processing. I know free applications that do this already exist. But, I'd still like to develop an application to help me learn more about avi's and to hone my programming skills a bit with a real project.I'm familiar with VB, so that's not a problem. I just don't know how to process an avi file nor how I would programmatically extract the frames from that file.Where should I start? What is required to extract frames out of the avi to individual jpgs?

I would like to develop an application that involves a lot of tables and maths, and then displaying the results. I can visualize how this would work in SQL, as far as creating the stored procedures and tables required, however the front facing application would be a completely new experience to me.I would probably be sharing the built application with friends, but completely as a no profit tool. I assume that the developer edition of dot net is a suitable option? My main query is, is dot net really the best way to develop this tool? I have a strong feeling that I will not be able to use SQL as this would require a server to be run, and this is not practical. Can the tables be implemented into a DLL or similar to be used by the application for example?

I need a little guidance here. What I am needing to do is develop an application which sorts text files, approximately 10 at a time.It would look something like this. (Using VBA 2008)The code I am having trouble with, is I want to be able to "load" 10 of these txt reports.I want the Sort button to trigger the application to run through each text file looking for specific keywords.
And finally, when all is said and done, I want it to export a new text file with the keywords listed that it found.I am just breaking into this and am super excited with how much I have learned so far!

About 5 years ago I wrote this program in Excellusing VBA to compute commissions, income and expenses for the real estate agents in my wife's business.The company is made up of about 50 agents. Part of the program includes a combobox on a main form when a name was selected it also selected, the agent id, and the split the agent was on. It would calculate the split expense that my wife got by multiplying the split percentage from the combobox times the total commission.The main form also contained various other comboboxes, list boxes, and text boxes to gather such info as property address, selling price, titles company, transaction credit,income,Once all the info was complete my wife was asked if she wanted to save the transaction. If the answer was yes, the info was transferred to the permanate database, a commision report for the agent and my wife was printed out, and the temporary database was cleared.

I am using Visual Basic.net 2010 to try to develop a simple VB application to control a data projector using RS232.So far, I have programmed the 'power on' button to open the serial port and send the power on command.The port opens successfully, but the projector does not receive the command properly, so it never powers on the projector.The RS232 command for power on is: BE EF 03 06 00 BA D2 01 00 00 60 01 00
My code for sending the command is: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
