View 8 RepliesI made my first app today. The point is to enter a password and then get into a screen that displays info, and you can edit it by typing in the text box. Is it possible to save the data typed?
View 2 RepliesIs there a way to save every time the user updates a textbox on the form? My reasoning for this is I don't want to lose all information typed into the form if they were to click on the "x" to close the form. I want the form to update whenever they type so if they forget to press a "save" button (or better yet not use a save button) the data won't be lost. I can use a textbox change event handler and code to update my dataset on every textbox in the form but it seems tedious.
View 2 RepliesI am trying to get valid data entered in a Windows Form.I simply used bunch of IF and ElseIF statements to set the conditions.
1. Because the field can only accept letters, I need to filter out characters. Eg: !@#$, stuff like that.
2. I need to apply a loop so that the user is prompted to re-enter the data or to have the error message repeat. Right now the error message display once and that's it.I understand the Do Until Loop but my book shows example only on numbers.

View 2 RepliesIs richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that?

I'm writing a windows forms project in Visual Studio 2008 - VB, data are stored in SQL database.- I have a date field within Datagrid that could be Null or have a date in it. I had set it to show <none> when it's Null (Null is allowed for this field). The problem that I got is when user would need to delete the date from that date cell within the grid. I'm getting an error immediately after pressing "Delete" to clear the cell value. I had put in a work around - added the code for grid DataError event and assigned DBNull.Value to that cell and user is able to type in <none> for that cell or just press save, but it won't allow to go to the next cell in the grid if you don't save or type <none>. I'm sure that there is a better way handlig situation like that. May be using different event? I wasn't able to find anything else on it.- the other issue in the datagrid - if user fills in 3 cells out of 5 for example and press save while in the 3d cell - it won't save the value in the 3d cell. I also put a work around to check for the values in specific cells before saving but the problem with it - few cells could be Null (and should be Null). I can't check every single cell value and force user to type something in it.

View 4 RepliesI'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?

View 3 RepliesI have a scheduling program here that shows you a calendar and let's you double click a time to open another form where you input the meeting information. When I click save it saves the person's name to the calendar view, but no details when I double click the entry again. What would be the best method of getting the other fields to save so they're there when I double click? Should I just somehow assign them to strings and return them in the right text box or would I need an array?
EDIT: Actually there is a database involved so I guess I have to get it to store the info in there first.
