hi there,
I am designing ASP.net over VB
I have a linkButton in the master page and it is disabled, in the login page the login Button must enable that linkButton
when I use it immediately like this:
stdMaster.ChangeModeBtn.enable(True)
it does not work , it gives me something about the protected withEvents "is not accessible in this context because it is protected"
I know that I am missing something but I do not know what is it
please tell me
urgent help please
There is always something to learn

ChangeModeBtn control, you are using is not a public control to access from the child page (Login). To access that control add a public subroutine or function in the Master Page which would enable or disable your control, like:
In MasterPage:
Public Sub EnableLink(value As Boolean)
ChangeModeBtn.Enabled = value
End Sub
Access the Link from your child page like:
stdMaster.EnableLink(True)
I hope this would help you.

I also have this problem. My research has shown that is is caused by ASP.Net opening two files and copying what's typed in one form into the other automatically. Yet when you attempt to reference a control from one form it states the above error.
My findings revealed that this problem has been around for sometime. It seems like there should be one simple correction to prevent this type of error from ever occurring. But thats just a dream.
I like to think that I understand the major parts of what causes the error. Yet the bigger question still remains ... how do I fix it?
Please help ... Thanks in advance.

I think the problem occurs just like "Venkatesh Mookkan" said , in the post reply
if your problem similer to mine, I think the method solution by Venkatesh Mookkan should solve the preventing, but taking care for the access control identifier to proper according to your application,
actually I did not fully understand your problem  , is it with button or with another control, is it from master page or something else,
clarify plz

You don't perform basic data validation like this in your database. You perform it in your web pages or in your middle tier. It is bad practice to send invalid input like this all the way to your database to be validated. Errors like this should be caught and handled far earlier in your application.

I agree. It is amazing how much bad practice I see around here sometimes.

Load Bitmap instance, and use Graphics.DrawImage() specifying the width and size. You can try GetThumbNail() also.

You can't crop an image in Javascript and unless you're writing a HTTP handler, or showing images in a web page with no text, you'll have trouble trimming them in memory and then showing them. What are you trying to do ?

Can't really do that. You did not supply a clear/concise need or database information at all. Code for storing data in a database depends on the schema, etc of the database. There is no one clear answer to your need.
