View 6 RepliesI have several text boxes that I will input answers into and I want them to catch the values if they are incorrect or correct.
Example: the user will input a Letter for the answer, A or a, and I was curious to how the correct input can detect if the answer is correct.If the answer is A B C or D then no message should display but when it's some other value this message will come up.How do I use true or false in this code?
Dim dbl1 As Double
dbl1 = CDbl(txt1.Text)

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I have an application in which I have two text boxes in which I enter name and age, after I enter the name and age then I click the Add button when I click the add button then the Name and the age should be displayed on the Datagrid contol in the same application. But the data should not get saved in the Database, it should just show the data on the Datagrid contol. And they have told me that its mandatory that I have to use the DataTable object.
And when i click the Commit Changes then only the data should get saved to the Data base...This i can do .

I have a Datagrid with 5 columns, one of those columns is the only one to have fixed values.Let's put this in a simple way, that column (lets name it column A) contains rows with values from one to ten.With an API call I get some information, lets say I got this:
1 - Andrew - 1.8
8 - Peter - 2.8
Something like this.The first number is equal to the value on the column A, the other two are name and height. I will note receive all the values (one to ten) with call or full information relating to all the columns.How can I assign the information I receive to the proper row based on one of the value I get with the call? Another thing, I will have to create a lot of rows, do I need to add them row by row?
