Using an ASP.NET User Web Control on a WSS WebPart

Ken Mazaika9-Feb-09 2:16

I've spent an hour trying to do this and I can't figure out what's going on. I have a class that I derived from Microsoft.SharePoint.WebPartPages.WebPart. I built the program, and copied the dll's to C:\inetpub\wwwroot\wss\VirtualDirectories\3141\bin. I registered the WebPart through a dwp file. The webpart works great (queries a database and outputs text).

I'm trying to build a User Control and include it in the webpart. To do this I put this in the Web Part's Render method:

<br />
                System.Web.UI.Control control = this.TemplateControl.LoadControl(@"WebUserControl.ascx");<br />
                Controls.Add(control);<br />

because of various examples online. Program compiles fine. I copied the WebUserControl.ascx all over the place to over all the tutorials I found that had it different places.

Before I copied it to a lot of places I was getting WebUserControl.ascx file not found. Now I'm getting the exception:

Request Failed

Anyone have any ideas about what I'm not doing right? I'm not installing the dll to the GAC, I'm not sure if that has anything to do with it.

Thanks,

-Ken

Ken, I could never do sharepoint programming. However, I know an easy way to use user controls in SP webparts.

Check this out. http://www.codeplex.com/smartpart[^]

This is the easy way to implement a .ascx as a webpart.

I didn't get any requirements for the signature

Hello,

If it happens avter you've typed some code, you need just to trace and debug the code. Here is a video how to do it: http://www.asp.net/learn/videos/video-10.aspx

If it happens just on a new application, and have not typed anything.. just repair your Visual Studio instalation, or uninstall it and install it again.

This error usually only occurs if the program is trying to execute some data memory blocks. Try this out-

1) Right click My Computer > Properties...
2) Click the 'Advanced' Tab
3) Under 'Performance,' click 'Settings'
3) Click the 'Data Execution Prevention' tab
4) Select 'Turn on DEP for essential Windows programs and services only'
5) Restart

This option is selected by default, but with installation of SQL 2005 or Visual Studio it can change and cause this type of thing later. Good luck!

Validating parameters and then passing as post parameter to another site

JacquesDP9-Feb-09 1:36

Hi Guys,

I have a page where I check if the user is logged on in the page load event, if the user is logged in then I get the user details from a database and then immediately want to send them to a 3rd party site using post parameters from the page load event, if the are not logged in then I want to continue displaying the current page.

To continue displaying the page that is busy loading if they are not logged in is not the problem, the problem I'm having is that if they are logged in I get four string variables, for example

string _a = "abc";
string _b = "def";
string _c = "ghi";
string _d = "jkl";

Then I need to send them through to another site. On the other site they are checking for the following post parameters (_a, _b, _c, _d), so how do I redirect to that url and sending those parameters along as post parameters?

Thanks in advance

If the 3rd-party site accepts variables in the query string then it's very straightforward:

string _a = "abc";
string _b = "def";
string _c = "ghi";
string _d = "jkl";

string postToUrl = "http://www.RayWampler.com";

Response.Redirect(postToUrl + "?_a=" + _a + "&_b=" + _b + "&_c=" + _c + "&_d=" + _d);

If your values could contain special characters then you'll want to url encode them:

string _a = Server.UrlEncode("abc");

If the 3rd-party site would only accept form POSTs then you'll need to use a technique like the one described in this article:

You will have to use CSS and the pseudo-class :visited to specify that.

Despite everything, the person most likely to be fooling you next is yourself.

By default when you click links on webpage visited link color change.
You can use this style in your header page.

a:visited
{
color:green;
}
