How To Make Text Fields Grayed Out Until User Tick CheckBox
Apr 13, 2010
I am building an application in Visual Studio containing various tables and input boxes. Its part of my coursework. I have a table that has two input text fields and above the boxes is a check box. I have created a calculation in VB that only includes the data in the text fields when the check box is ticked. What I want to do now is have the two text fields as un-editable until you tick the check box? or greyed out?

I was developing my own project in the university so what i am stack is to have save button which firstly validates what the user enters the form. for instance if the user skips the text fields, i wanted to restrict the user to fill all the form and when he completes, the save must be accomplished.
Here's the code i was trying to put but i was having problem saying the windows.forms.etc is unable to convert the save as Boolean and something like that.
Dim success As Boolean
Private Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click

I have three checkboxes on my datagridview namely, Yes, No, Inv. If the value is set to True in the table which populates the datagridview the respective checkbox is checked and if false unchecked.Now, when on runtime I try to check a checkbox on the Yes Column I receive the followinf error;
DataGridView Default Error Dialog
The following exception occurred in the DataGridView:
System.FormatException: is not valid value for Boolean. -->System.Formatexception: String was not recognised as a valid Boolean.
at System.Boolean.Prase(String value)
at system.componentModel.BooleanConverter.ConvertFrom(ITpeDescriptorContext context. CultureInfo culture, Object value).........
The No and Inv allow me to check and uncheck the checkboxes as many as I want without generating the error.

I'm in the process of designing a game, how can i make the game tick over in time?
First thought would be a timer but is this the correct way?
Also I'm looking at building this game in WPF, By memory WPF does not have the timer control, what would you do then?

experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database? In short, I'm about to embark on this little Office automation excursion and I'm hoping a little bit of feedback here.

I am trying to make a application that will bind User Desired Keys to User Desired Text. This is what I have done so far, it is not very much but it keeps crashing and visual basic is not telling me anything is wrong with it. I basically just want the user to be able to select a hotkey from a combobox. [code]

I am developing an application in which I would like to let the users design some forms and decide the fields that are in the form.An example is better than a poor explanation, so let me put the example of Microsoft CRM in which you as end user can define a form, the fields in that form, or customize existing forms by adding or removing fields.
