View 1 RepliesI am a newbie using VB.net in VS 2008. I took over a vb.net winform application that has a binding navigator in it. The users wanted to add 2 new fields to the form. I added the new fields to the SQL Server 2005 database. I refreshed the Data Source tab in the project. It recognizes the 2 new fields.
I dragged them onto the form. When I go to add a record through the application, it does NOT save these 2 new fields. I check the properties for these 2 new fields under "Data Bindings" and it shows under the "Text" property the correct Binding Source and column name. I need to store these 2 new fields to the table.
I am currently developing a WPF application that will utilize existing WinForm dialogs. I'm experiencing a long lag between the time I call ShowDialog() on a WinForm to the time it is displayed.Even when reusing WinForm dialog objects the lag time is nearly as bad on the second hit. Meaning that the problem isn't in the constructor. have a work around to increase speed or know why the speed is so slow?

I would like to make the Tab movement can also pressing the "Enter" Key. I have google and found the code which possible to used. But I found its not running fine with me. When I press "Enter" key,it runs fine for the tab movement. But if I put something into my textbox,it only allowed me to put 1 character and it will move next.

If Keys.Enter Then
SendKeys.Send("{TAB}")

How should I do to make the "Enter" key press work as tab?

I have a visio flowchart that represents sequence of questions to enter an order. I wrote a VB 2008 program, that represents steps from this flowchart in a wizard-like questionnaire. Now I'm asked to represent this flowchart graphically in a window,and make each step clickable. Clicking on a flowchart box would open the relevant wizard page. Can someone suggest how I can accomplish this, or know of some article or example that would point me in the right direction?

View 2 RepliesWhen a user click the .msi, i want a folder called "Your Files", which comes with two small images by default, to be created in C:UsersYourNameDocuments. In short, MyDocuments.
What i did is put the following code in program.cs:
string myDocuments = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
string downloadArea = System.IO.Path.Combine(myDocuments, "Your Files");
System.IO.Directory.CreateDirectory(downloadArea);
Just before:
Application.Run(new mainForm());
The problem is, this folder will be created every time the user runs the application which is not a good solution, also in this case there is no place to load the two images so it can be loaded while the folder is created. I want the folder to be created once preferably while installing the application, so even when i uninstall the folder "Your Files" and its sub files be deleted automatically along with the program files. I tried to do it via Setup Project, but i couldn't.

View 2 RepliesI want to create an icon for my winform application. What are the common tools to create icon for winform?
View 3 RepliesI run the app under current logged in user from the service.To give you background, I have a VB.NET Windows service whose sole functionality is to run a Winform App at a specified time. Apart from that it also sets a system wakeup timer so that the system can be woken up at the specified time, if it goes into standby/sleep, to run the app. This service has to cater to XP/Vista/Win7 desktops on our network. This service won't run on servers and laptops.
The Winform App shows a UI for the user to provide some inputs. If the user does not provide the input within 15 minutes, then it defaults the value and then goes into system tray icon. The user can click on the icon and change the values later (within in a specified time frame and that too only twice).
There is absolutely no interaction between the service and the winform app apart from the service starting the app. It also monitors if the app has been killed by the user/crashed. If it has been killed/crashed, then a new instance is run after 30 mins from previous run.
If there is no user logged on, then also I want the app to be run at the specified time. As I said before, the app has a default timer. So if some user has just logged off from the system, then defaults would be set by the winform app.Now coming to why I am stuck with this design - I cannot use TaskScheduler because it has been disabled on all machines and security team is not willing to change it. TaskScheduler had the option to wakeup the machine from sleep and other things. So basically I ended up creating a service which is acting like task scheduler.
Currently when I run the app.exe via process.start() within the service, its running under SYSTEM account as the service is also running under LOCAL SYSTEM. So basically I am not getting any UI. Is there anyway to run it under the current logged in user? I am not worried about multiple user login as we wont be running it on servers and switch user is not enabled on our desktops. Even if somebody has done a remote login via mstsc, then also I need the run the app and show the UI to the user.

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 envisioning this as an add in developed for Visio.To Summarize I would like to be able to list the steps of a process in Excel, and import the excel sheet into Visio. Finally I would like Visio to generate a flow chart based off of this imported data.I have developed a more detailed flowchart as to how I think this should work as well as a sample Excel sheet.

I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated.Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion:
public void Update(int cusID)
{
SqlCommand objSqlCommand = new SqlCommand();
Customer cust = new Customer();
[code]....
The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated!
A year ago I saw a beautiful simple code that gets a data table and saves it in an excel file. The trick was to use the web library (something with http) and I'm almost sure it was a stream.

what tools do you use to create programming flowchart/documentation from VB.NET source code? There are absolutely no comments/documentation at present. I am a beginner, i.e. I tried Sandcastle but it is way over my head and could not get it going, not even with GUI.Fatesoft's CodeVisual To Flowchart is OK but it is almost the same as the code and I still don't understand the code.
View 3 RepliesHere's the scenario, winforms application, monitoring via Task Manager Processes Tab.On initial launch spins up to ~61,000K (initial data grid and data loads)If I minimize the application, not touching or doing anything the Mem usage drops to 1,380K.When I restore the application is spins back up to only 5.8K
So my question is, does the minimize send some internal message to clean up resources since the application in question is not in focus?The first app I noticed this in happens to be VB.NET, but I've observed the same behavior in my main C# winform applications.
