Hello,
I hope you can help me with this issue. I am trying to build an application in C# that converts text from XML with an XSL to a HTML file and prints it according to some printersettings that can be made by an user interface. This application needs to run as an automatic process, so user intervention is not preferred.
I managed to get the XML+XSL->HTML conversion working with the following code:
public static StringWriter MergeXSL_XML(string xml, string xsl)<br />
{<br />
try<br />
{<br />
XPathDocument xPath = new XPathDocument(xml);<br />
XslTransform xTrans = new XslTransform();<br />
xTrans.Load(xsl);<br />
StringWriter strW = new StringWriter();<br />
xTrans.Transform(xPath,null,strW);<br />
strW.Close();<br />
return strW;<br />
}<br />
catch(Exception e)<br />
{<br />
MessageBox.Show(e.ToString());<br />
return null;<br />
}<br />
}<br />
The XML and XSL are read from a file or database. This is working correct. The string writer contains the information I wanted as HTML. But now the bottleneck, I cannot print the HTML.
On some sites and newsgroups people run a command through the shell that executes the printer option. But this needs a temporary file on the server, but that’s not what I want. Some also use:
<br />
wbElement.QueryStatusWB(SHDocVw.OLECMDID.OLECMDID_PRINT);<br />
But that does not give any satisfying results.
I already managed to place the HTML in the Active X component
<br />
wbCom.Navigate("about:blank");<br />
mshtml.IHTMLDocument2 hDoc = (mshtml.IHTMLDocument2)wbCom.Document; <br />
hDoc.write(html);<br />
The item shows the HMTL, but I cannot request the data later (when requesting wbCom.Document I won’t get my edited document), but that is not the real problem. The real problem is that I cannot parse the document to the printer. There is a print document method in the item:
<br />
hDoc.execCommand("Print",false,0); <br />
But calling it shortly after the placement of the HTML in the document will cause a empty document to be print out. But by pressing a button to start the print will print out a document. I already tried to insert a small sleep, but how long the sleep does not matter, an empty document will be printed.
The thing that I want is that the document can be parsed to a printable document so I can print it with the default print components of C#/.NET. Casting does not work, I tried all the IHTMLDocument* classes to find something useful, but none of them seem to have a usable function to create a printable document for the printer components in .NET. One of the casts I tried:
<br />
MessageBox.Show(hDoc.ToString());<br />
printDialog1.Document = (PrintDocument)hDoc;<br />
printDialog1.Document = (PrintDocument)hDoc;<br />
hDoc.execCommand("Print",false,0);<br />
Another problem is that it seems I cannot change the printer settings, I need to change the default printer settings in windows. For example, I need to change the paper source, I can request the sources via:
<br />
for(int i=0; i < printDocument1.PrinterSettings.PaperSources.Count; i++)<br />
{<br />
MessageBox.Show(printDocument1.PrinterSettings.PaperSources[i].ToString());<br />
}<br />
But I am not able to change them
Can someone help me with this problem?
Thanks in advance…

I'm trying to double buffer an entire form (i.e. all the controls into one off screen buffer). I've tried using the SetStyles double buffering but that appears to double buffer on a individual control basis and not work at all on the ListView control.
Has anyone done this before?
I'm heading in the direction of overriding OnPaint on the form itself and somehow force each control to draw into an offscreen buffer I created. When that's done draw the offscreen image on screen.
I don't have this working yet but thought I throw this out there incase someone has tried this already or has a better solution.
Thanks.
Kevin

Hello all,
I am new to C# and trying to write a program that will strip data from three different reports (2 Excel, 1 Text), then output the three "modified" reports. I can picture the flow of the GUI, but cannot seem to grasp the capture and massaging of the data itself.
Any suggestions would be helpful

Welcome to c# world!
Your request is very vague. Why not ask a more specific question, like how do I open an excel document in the app? Most things you can find by doing a search of the forums, you would probable find most of the answers you are looking for.
Most here are helpful, if you have specific questions...
Some resources:
Excel: http://www.codeproject.com/csharp/csharp_excel.asp
String handling: http://www.codeproject.com/books/0735616485.asp
Hope these help.

I have been playing with the different events, but am not sure how to make this happen. I want to select the item currently under the mouse. This would give a highlight effect to the one you are over. Anyone know how to do this?
Thanks in advance.

If you've not already found a solution, try looking at the OnMouseMove event. Are you trying to give feedback for any control on a form as the user moves from one to the other or are you trying to do this within a specific control, like a ListView or ListBox?

Hello everybody,
I'm building a class library and i would like to add summary information to some function/classes, the ones that are shown by the object browser. When I add the summary information it is only available to me in the object browser when I'm working in my library.
I would like to see the same information in the object browser when I add the library to an application.
Can somebody please tell me how to do that.
Regards,
Paul

Hi,
Guess the following code will help you.
string hostname = "";
hostname = Dns.GetHostName();
MessageBox.Show(hostname.ToString());
Thanks and Regards
