Hi All,

I have a code that requires users to fill in every field in a form, and if any field is left blank then a message will prompt users to enter data in that field.

My problem is after dispaying the message the form dissapears and the code continue execution, which does not allow the user to respond.

I wish to know:
1. if there is a way to highlight the blank fields
2. how to stop execution until the user enters the required data

I would appreciate it if you could help.

Thanks
Khalil

Thank you for the reply. Unfortunately I am unable to find the control Validator. My version is 1.1 not 3.5, and I am guessing this is probably the reason.

Then why do you post in a .NET 3.5 forum? That's quite confusing.

Anyway, these controls already did exist in 1.1.

Maybe you're simply not checking for IsValid?

Guys,
The quote below is taken from the link that you provided me:

To install the control into your environment, open the Toolbox. Then select the tab you want the control to appear in, right click, and select �Add\Remove Items��. When the �Customize Toolbox� window appears, select the �Browse�� button. When the �Open� dialog box appears, navigate to where you have placed the TextBoxValidate.dllll and click the Open button.

When I go to Add/Remove Items, I cannot find the "TextBoxValidate.dll".

Please note that I am new to this language and may not understand everything you say; you will have to forgive my ignorance.

I would appreciate it if you could provide details.

Thanks

I think you missed the intro of that paragraph:

Quote:

To use the TextBoxValidate demo program, make sure both TextBoxValidateHost.exe and TextBoxValidate.dll are both in the same directory,

In other words, the DLL comes with the article and demonstrates custom behavior explained in the article.

It would help if you provided a lot more information. Posting in a 3.5 forum when using 1.1 is confusing, but not even telling if this is about Web Forms (ASP.NET) or Win Forms makes it almost impossible to answer your questions.

So, please provide more information, tell us what you're doing exactly and trying to accomplish, be specific, and we might be able to help you out.

Cheers,

Imar

Hi Imar,

In response to your reply, please note the following:
I have a form with ten fields attached to the form, where the user will be required to fill in each field and then the entered data will be transferred to an Access file using OleDbConnection.
In case if the user misses one or more field, a message will be displayed prompting to fill in every field. Up to this point my code is working fine but then the problem is that my code does not allow the user to fill in the empty field/s and the form dissapears.
I wish to show the user all empty fields and let him complete the task before execution is complete.

I hope you can help me.

Thanks and regards
Khalil

Thank you for clarifying validation....

But this doesn't really say anything, does it? The description you just gave can equally apply to a paper tax form.

So, tell us what technology you are using. Web Forms aka ASP.NET? Win Forms? And why are you still using .NET 1.x? Have you looked at the various tutorials on Validation in yoru technology? What have you tried so far and what does your code look like?

Etc etc etc
