ASP.NET Discussion Boards

You should use the standard asp.net login control and then through the web configuration you can then asign rights to users.

If you dont want to do that use the following:
Put a column in your login table and call it permissions, then set the permissions as so:
User1 rights = 0
Admin rights = 1

then just check this value in your c# code e.g.

if (rights = 1)
{
txt1.enabled = true;
}
else
{
txt1.enabled = false;
}

something like that, remember what Ive written is half pesudo code so you just need to amend that
Smile | :)

Please don't ask variations of the same question over and over. Continue the discussion where it was started. If you want quicker answers, ask clearer questions to start with.

Your best bet is to build the lists yourself, not try to auto generate them.

Hello friends.......
I want to move some text from one textbox to another textbox on onblur event..
I have this javascript code that is working perfectly with the HTML controls
function putMailid()
{
var x=document.getElementById("txtLogin").value;
document.getElementById("txtEmailID").value=x+"@gmail.com";
}

but i don't know that how to use it with asp.net textboxes..
Bcoz there is no Onbluer event......
Plzz help me out

I recommend you do some reading on ASP.NET. Basically, just because the IDE doesn't show you an event, doesn't mean it doesn't exist, it just doesn't exist on the server side. You can add an onblur to a textbox, and it will be passed to the client and work perfectly.

Your next problem is getting the cliend side Id of your textboxes. This is represented by the ClientID property of your server control. You need to write that to the client, either inline in your script, or as script that creates js variables you can use. Also never call document.getElementById and assume it returns something, add a step that checks it.

Hi,

how to get the Process name which is accesing/ using my file. I want to get the process name which is reading my file using web application

Thanks in advance

What you want is impossible. A web app runs in the browser, and cannot enumerate processes on the local machine. Why would you want to do that ?

Hi
I have the following code:
When it runs I get the error:
<b>System.InvalidCastException: Specified cast is not valid.</b>

chkIgnore = a checkbox
Ignore = a field in a database type nvarchar size 1, can either have Y or N in the column

If anyone can help that would be great, bit stuck on this one.

thanks! Smile | :)

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
bool ignore_box = true;
if (DataBinder.Eval(e.Row.DataItem, "Ignore") != null)
{
if (DataBinder.Eval(e.Row.DataItem, "Ignore").ToString() != "Y" || DataBinder.Eval(e.Row.DataItem, "Ignore").ToString() != "N")
{
ignore_box = (bool)DataBinder.Eval(e.Row.DataItem, "Ignore");
}

if (ignore_box == true)
{
((CheckBox)e.Row.FindControl("chkIgnore")).Checked = true;
}
}
}
}

You're calling this method three times because...... ????

You're assuming because the the field is not a string starting with Y or N ( and not y, n, t, T, F, f, or any other letter or character ), it must be a bool. Either your data source is seriously messed up, or your understanding of how this works is. Judging from the error message you're getting, I'd say the latter. You can't just convert anything to a bool, it has to be a bool. It's obviously not. At a minimum, you should put this code in a try/catch, and then set a default. Probably, you should replace it with a default.

Hi
I managed to sort it

The database field was set as nvarchar so I changed it to bit.
Then I changed or the N and Y to 0 and 1

Its all working now!

Its always better when you fix it yourself Smile | :)

Yeah, doing it right in the first place helps Smile | :)

Does anyone have any idea how I can set a transparency key for an image (Most likely white or, my favourite, Fuschia) - Normal C# has the .MakeTransparent(Color.Fuschia);, yet the ASP.NET Image boxes seem to lack the method...

I have code to pretty much create small images over a large image, which are being loaded from the web, and they're not exactly square, and these random white boxes are... disorienting Wink | ;)

Maybe a way to customise a .jpg to be transparent by default, and THEN upload it... ?

Any help would be GREATLY appreciated!

I believe that later versions of IE support transparency in PNG images.

Also, ASP.NET is constrained by what HTML allows.

Well, it seemed it needed an actual transparency settings.

Paint.NET's transparency function worked wonders Big Grin | :-D

Thanks anyways Big Grin | :-D

If the control is a CP article, ask in the forum provided by the article. If not, look for a forum where you downloaded the article. Most people here will not have used it, so how can we help ?

Ah - the problem is that you're trying to use a windows control in a web application. You can't do that.
