Adding a button to a table created in codebehind

You can call the javascript methods to fire validation directly. It's Page_Validate(), I believe.

I have created a table that pulls from a database of users' comments. As it is sort of a wiki, I want the user and/or other users to be able to edit the comments once they have been posted. However, when I try to add an Edit button, it requires that I append .toString(), which causes the button to appear as System.Web.UI.WebControls.ImageButton instead of an actual working image button. Is there any way to add a button that actually works? And, yes, I am aware that the code is incomplete and that the button does not currently DO anything. Smile | :)

Right now I'm just trying to make it show up. Any help would be greatly appreciated.

while (reader.Read())
{
	HtmlTableRow r = new HtmlTableRow();
	HtmlTableCell c0 = new HtmlTableCell();
	c0.InnerText = reader[0].ToString();

	HtmlTableCell c1 = new HtmlTableCell();
	
	// Troublesome part...
	ImageButton a = new ImageButton();
	c1.InnerHtml = a.ToString();
	// I also tried c1.InnerHtml = a; and countless other variations
	// End troublesome part

	r.Cells.Add(c0);
	r.Cells.Add(c1);
	table.Rows.Add(r);
}

Have you tried c1.Controls.Add(a) instead of c1.innerhtml =

Removing anonymous access to web service

HI,

we have a web service and our application(.net 1.1, C#, oracle) consumes this web service. By default the security(authentication) is given anonymous, now as for security reasons we want to remove this option.

So lets say we use Integrated Windows Authentication. Doing so we would get Access Denied 401 error. On searching though it is found that we could pass few credentials and access the web service (this works fine)

What are the cons in providing user credentials in the code?
What are the steps to be followed to make a web service secure and accessible?
Is there a way that a web service can be accessed after removing anonymous access and not providing any credentials in the code?

Image to PDF

I have a web app. where I take user information and create a business card image. My question is, How do I convert that jpeg image I have into a pdf?

From whatever image editor you're using for your jpg, you can convert the image into a pdf by going to the Print menu and selecting your pdf maker. I use Adobe Acrobat and highly recommend this, as it creates smaller, clearer files. However, there are also several free pdf creators on the intranet, such as www.primopdf.com, www.cutepdf.com, etc. If you're wanting to create the pdf automatically as part of the application, I'd need more information about what language you're coding your program in.

I got the source code from someone in Code Project and kind of made my own thing with it, but like I said before the graphics dept. is unable to use the jpg image because when they convert it to cmyk all the brush strokes show up and we can't have that. Any suggestions at this point would be greatly appreciated.

Thanks,

It seems to me that you probably just want to create the PDF ahead of time, seeing as all these paths are hard coded. You also shouldn't be doing this sort of heavy lifting in your presentation layer.

If I can some how raise the DpiX to 300, and the DpiY to 300 then I believe this will all work.

The DPI of a monitor is typically 72 or 96. DPI is actually just rendering metadata, it's got nothing to do with the file itself ( that is, it's independant of resolution )

Ok, so how would I go about fixing the garbage around the text. I've tried playing around with the smoothe antialias option and things of that nature, but have had no new results.

Christian Graus4-Oct-07 12:13

4-Oct-07 12:13

antialiasing is different to noise removal. I don't even know what garbage you're talking about, is it on the jpeg, or just the PDF. DPI will not resolve this either, you need to work out what the noise is, and remove it.
