Converting MS ACCESS Application To Windows Forms Application?
Jun 23, 2010
My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form.

Final step in my application. I finally got all the requirements working, but now I need to have the application run in the background.
The application was written in Visual Studio 2010 VB, Win form app.
The requirements are as follows:
1.) run the application at start up
2.) no icon
3.) always in focas
4.) always runs in the background.
Here's the full code I have right now (working! whahoooo)
Public Class Form1
Private Property count As Integer
Private s As New Stopwatch

I only managed make the form always on top. But what I want is when the form is on top, user cannot access the other application in the windows.
For example : Some messagebox won't let users access the other application until the users hit the OK button.

I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

I have been developing a VB 2008 application which has been using Access as its database. The app is very far a long with about 30 forms and 45 DataSets I now must change the application to use SQLServer. Unfortunately all of the Table & Attributes names have changed in the new DB. Almost all of the data model has stay the same.
I have a few questions on the conversion.
The ConnectionString is currently pointing to the Access DB. I have entered the new ConnectionString into the Setting tab. What is the best approach to make the change?
I have done some testing to change the Table & Attributes names by using Quick Replace. It seams that sometime when I would do the rename I would lose the TableAdepter on some screens.
What is the best approach to performing the renaming task?

I have an application that I created a while ago. It's a forms based application that runs on one of our servers at work. The app works well, BUT at the moment, requires someone to manually run it, which means having the admin account always logged in, but having the server locked.Although it's a forms based application, for the majority of the time I don't need to see the forms, so can I safely make this run as a service (by adding the appropriate code), and hiding the forms?Also, is there some code I can put in to test whether the instance of the program was started as a service or from a user double clicking on the icon? If so, I'd like the user initiated instance to run with the forms visible.

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.

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 Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using
System.Windows.Forms.Application.Run(General)
General is a form but also a class, so I wonder what it the pros or cons of using :
System.Windows.Forms.Application.Run(General)
vs
Dim gen as general
System.Windows.Forms.Application.Run(gen)
In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable.

We have an application in Access for UI and MS Sql server as Database server. We now decided to build a new application in web application for UI. This web application is only used by the employees who work for the company. But later we decided to host this web application on outside server. So the user (from this company only.) can able to login anywhere in the world. First I thought creating the web application using 'windows' authentication thinking we may be using it as an intranet web application. But now my manager asked me to use both 'Forms' and as well as 'Windows' for using this application and this web application will be hosted on outside server. I really don't catch his point of using both types of authentication.

I have this code and I hope that this is correct. I build a dll component from the class file that contains this code and I am trying to use it as a reference in windows forms application. I have allready made this forms application and added the ddl to the reference but I do not know how to use it in there. I would like to activate (insert value 1) inputA & inputB using checkbox and that the outputQ is displayed in textbox (1 or 0). Do I have to use a vb interface to do this? And how can I use this code as dll component in the forms application?

I'm trying to design a windows form application. By default, .NET had put Tahome 8,25 on toolbar and Microsoft SansSerif 8,25 on everything else. To improve general look and feel of the forms I'd like to change them.
Which font family should I use as a default? And what size should they be?
For:
Classic data input form (label + textbox, label + combobox...)
Data grid
Is there any recommended way?
Application is a classic business app, you can think of it as an accounting type.

How can you write a VB.NET Windows Forms Application via CodeDom? I have tried everything, the closest i got to it is the code below, which first of all shows command prompt window which is not good, and then shows the form for like a second and everything disappears.

I have a windows forms app (32 bit) written in VB2010 which occassionally hangs in windows when minimised to the task bar You click on the icon on the taskbar and it will not come back up on the screen
No other modal forms are open in the application when the hang occurs Other programs respond OK
I ran Process Explorer against when it was Hung but do not know how to interpret the stack page, or even if it is helpful STack page with my application selected and Threads tab selected with CSwitch Delta column sorted descending. Then double clicking the top entry (my application .exe)
Note: This is running on an x64 machine, but also hangs on x32 machines

I want to allow the user to write a little script (JScript, VB, whatever) with a function called by my application that returns an XmlDocument object (a string would be ok).I did some research, and it looks like the scripting engines are obsolete.
The best solution I could find is here: [URL]..But I was wondering if there is a better and more "official" way.

I understand that I cannot use the System.Console to output information from a Windows Forms application because the standard input, output, and error streams are not run through the console in winforms apps. But I can't seem to find any documentation on where the standard input, output, and error streams are being directed to! Basically, I have a winforms app that accepts command line arguments and can be run in batch mode, however, I just want to direct some feedback to the user based on whatever method they're accessing the program. The app is used to redirect a client-server application from one server to another. In some instances, the user does it by hand (with a mouse), and other times they're doing it in batch mode (using SAS, command shell, VBScript, etc...). In those instances, I'd prefer NOT to use MessageBoxes because it will kill any processing they're doing.

Creating a pdf document using Itext is quite simple if your application is a web application because you can find samples to help you out all over the web. Creating a pdf document for a windows application on the other hand is not so easy. I cannot find a single sample online anywhere.so far this is what I have:
Private Sub PrintDefaultReport()
'Declare PDF document
Dim doc As New Document(PageSize.A4, 40, 40, 0, 35)
Dim MemStream As New MemoryStream

m planning to make it as such:1. BLL and DAL are on the same box.2. Only PL is installed on client machines.Simple enough. Right now am planning to go web service as I have no idea how to do this with windows forms. So in a nutshell, my question would be how to connect the PL to the BL and how to do this during the development stage. I was planning on deploying the BL as a webservice then during development, the PL sets a reference to it to get the data.Data will basically be datasets, datatables etc. Might also have a need to do some file transfer.
