Streaming Content From (sharepoint) Web Part
Mar 22, 2010
How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end.
This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

We have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?

When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.

I have a need to integrate a third-party Java applet into a custom web part I wrote for SharePoint 2007. The web part simply loads a user control I created that contains the bulk of the functionality, and that's where the applet will go. I added it to my user control project and it works fine outside of my SharePoint environment.
I installed the updated web part onto my MOSS 2007 development site and the part's page loads fine. The applet is triggered by clicking a link button on the page, which runs some client-side JavaScript to start it. The problem is nothing seems to happen when I click the link. No error messages appear, and the stuff the applet is supposed to do never occurs (it's for doing file transfers via FTP). I have the .jar file as an embedded resource in my user control DLL, which is deployed to the bin folder, and SharePoint fully trusts this DLL.
I used Firebug to step through the initialization code and I saw an HTTP GET that failed with a message about not being authorized, but it didn't give any details and I'm not positive it was related to the applet. Is there anything special I need to do to make the applet work? Or am I going about this the wrong way?
EDIT: The problem turned out to be the .jar file for the applet couldn't be found. SharePoint is clearly doing something different here, and I need to find out what. Can Java applets be used within a SharePoint site? This question suggests they can, but in that case a Page Viewer web part was used, which isn't going to really work for me.

Is there any way to restrict a web part to a certain zone? I know I can restrict it by using the AllowZoneChange flag, but is it possible to make sure the web part can only be added to certain zones? I have some web parts which are only viable in a wide column (zones), so I want to make sure that no one tries to add the web parts to narrow columns (zones). Is there any way of accomplishing this?

I've created a quiz web part in SharePoint 2007, but am stuck on one permission. It needs to write the quiz score to a list, which it's throwing an error now when trying. I'm under the assumption that if the web part has the appropriate permission level, the user's permissions (the quiz taker) don't matter. Is there a particular permission that should allow the webpart to write to a list? Specifically:

Has anyone had issues with streaming CSV (or TXT) content to the browser over SSL/HTTPS.
There are no issues when running my code in Firefox - i've found a bunch of issues, all seem to be solved for people using PHP.
this.Response.ClearContent();
this.Response.ClearHeaders();
this.Response.Buffer = true;
...
this.Response.AddHeader("","") // headers
this.Response.Write("TXT STRING GOES HERE");
this.Response.Flush();
this.Response.End();
I've tried all different headers to remove the no-cache, pragma ...etc.

I currently have a client with a SharePoint site that wants to incorporate an (already written) ASP.NET application within a webpart in the SharePoint site. The ASP.net application currently uses an IIS impersonation account to connect to the SQL database.
Some added functionality the client is requesting would require me to grab the user's windows login identity to use the SharePoint UserProfileWebService to query the PropertyPages for that specific user. Because the (already written) ASP.NET application uses impersonation, when I grab the WindowsIdentity.GetCurrent().Name, I get the impersonation account and not the actual user's account.
Is there a way to keep the current setup (impersonation account on IIS to connect to SQL) and still grab the logged in user's credentials? Or would a better way about this be to change IIS to consume the Windows Identity of the logged in user and encrypt the connection string in the web.config?

I have a web part that is deployed in a MOSS 2007 application. The web part has a text box for entry of an ID number and a button that fills a dataset from the db based on the supplied ID and binds this to a details view. The details view is a private variable declared at the top of my web part class, the details view is then instantiated and various properties set along with the event handlers in the CreateChildControls() Sub.
[Code]....
The details view is then rendered in the RenderContents() sub.
[Code]....
After checking the user inputted ID number for malicious chars I fill a data set.
[Code]....
The problem is that when I click the auto generated Edit link nothing happens and if I then click it for a second time the editable text boxes appear but have no data in them and my data key appears to have been overwritten. I have also tried entering new values into the text boxes and clicking the Insert link and then looping through the NewValues collection inside the ItemUpdating event but this displays nothing!

I used to deploy developed web parts to a remote sharepoint site by Build->Deploy menu inside Visual Studio 2008 months ago ( I am not a regular web part developer). My network engineer also asked me how to deploy web parts without stsadm commands. anyway now I can't. Visual Studio keeps complaining that the specified site doesn't have sharepoint site contained. "No SharePoint Site exists at the specified URL."
After googling, it is said web parts can't be deployed to remote sharepoint sites from visual studio. Only can to local site. However I did it before. Visual Studio 2008 service pack or hot fix made this feature (remote deploy) removed? Or is there any workaround?

There is also another page, named Default1.aspx, which is son of MasterPageB.Master.
I need to access to a label control put in the Content part of MasterPageB.Master.
I tried to fit the code that I usually use for one level (Master-Son) found at this page and I've write in Default.aspx.vb this code:

I have deployed a custom SharePoint Web service on Farm A. I am trying to access this Web service from a SharePoint timer job on Farm B. On Farm B, I am creating Class Library project, packaging it (wsp) and then deploying to GAC. The problem is I'm unable to access the Web Service using the following code. TodaysNewSVC is a service reference
TodaysNewSVC.GetTodaysnewsfromInsite objGetNews = new TodaysNewSVC.GetTodaysnewsfromInsite();
objGetNews.PreAuthenticate = true;
objGetNews.Credentials = CredentialCache.DefaultCredentials;
objGetNews.Url = "http://insite-dev.portal/_vti_bin/todaysnews.asmx";
DataTable dt2 = objGetNews.getNewsFromInsite(true, true);
//getNewsFromInsite is a WebMethod which returns the DataTable.
Note: Both farms use the same active directory authentication. I have also done the debugging for Timer Job and feature activation and they are working fine. The problem occurs during the call i.e. getNewsFromInsite
The asmx and wsdl files are accessible from Internet Explorer and also from Windows Console application. Here is the code which I use from console application:
GetTodaysnewsfromInsiteSoapClient objWSClient = new GetTodaysnewsfromInsiteSoapClient();
objWSClient.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;[code]...
Here is the error message:The request failed with the error message:

I have a site with potentially very long running SQL queries and verification process. The user would have an idea how far along they would be by the part number currently being analyzed in the process. I've done a lot of reading and have determined that setting up a two way socket with the client would be the best way to communicate this information to the user. Are there any vb examples out there on which I could base my code?

Does anyone know how to do this without saving the file to the server but rather just streaming it to the user from memory?
My below code is working
streaming directly from memory instead of using physical path of server machine then saving the file on client machine
Private Sub generateExcelSheet()
Try
Dim weekFrom As String = DdFromWeek.SelectedValue
Dim weekTo As String = DdToWeek.SelectedValue
