I've already given you lots of advice.
Your query should not be returning passwords. It should probably just be returning the MemberID. If no rows are returned then obviously the login has failed.
You should store the memberID in the session as that will be connected to other parts of the system. (Assuming the database is well designed)
You should follow the other advice I've given, especially about SQL Injection Attacks. Your code is very weak and quite vulnerable to attack.

If you are dealing with regular textboxes, all you have to do is to either set the "Tab Order" for the fields, or force focus to the field you want using:
<br />
[Field Name].Focus()<br />

You should change this to:
strVerifyMbr = "SELECT MemberId FROM datMember WHERE memberUserName='" + txtUserId.text + "' AND memberPassword=' + txtPwd.Text + "'"
However you are susceptible to SQL injection attacks if you try this approach. You should consider using stored procedures for database operations and pass parameters to them.

Hi,
As we have AutoGeneratedColumns property in GridView of ASP.Net Framework can we have the same functionality in vb.net ???
Thanks
|
|
|
|
|
VB.NET has nothing to do with it.
Yes, auto-generated columns exist with the DataGridView in Windows Forms. In fact, if you don't supply columns yourself, autogen'd columns are made by default.

hi all
i have to autogenerate invoice no which should be alphnumeric.
Had any one idea about how to autogenerate IDs
poonam

Where is this invoice number being generated from and what are the constraints?
I presume it will be generated in the database, in which case you can use an identity column. If that is not an acceptable solution then you need to give more information.

If this does not work why not just use a varible as a counter if you creat it as a user varible it will hold even when the program shuts down. that way if you need to you can reset it programicaly the only problem i could see with this is if you jumped the app to a different system but using the same db

What exactly is a "user variable" and how is it different to any other kind of variable?
How does it hold on to the value when the program shuts down?

Does anyone out there have a VB.NET code sample that allows me to modify WMA tags (WMAID3Tag, e.g., Title, Artist, Genre, etc.) and save them back into the WMA file? I've found plenty of samples of code that reads these tags, but none that write changes back to the file.
Thanks,

Hi,
I am upgrading an ms access application into .net2005.
The problem now is that one of the report from the current access
application is exported into .snp file(snapshot),
which is currently not supported by .net only (xls and pdf)
Does anybody have an idea on how I can export my report in vb.net into
snapshot format? Your idea will be much appreciated. Many thanks.
My second option here is to create a macro in access that will be called by my vb application to export the report to snapshot format. I will create a temp table in access to receive the data to be converted.
The problem is I do not know how to do it.
Does anybody knows how?
Thanks in advance..
best regards,
king

Help!
Have searched the web to no avail for a solution to this issue. There seem to be a few people having the same problem, but none of the suggested solutions seem to work for me
Have been forwarded code and added it to an existing solution (3 projects), but the original(?) doesn't seem to update any changes (including commenting) made in the code. When debugging the IDE steps thru code i've commented. It was looking for the (non existant on my machine) file path to classes etc, but have deleted any references to them, and have no idea where to go from here.
Thanx in advance to anyone who has successfully resolved this and can help out.

If you're building a release version, the debug version won't update. If you've added a reference to the release version to your project, building the debug version will not update that dll for debugging.
