Hello,
I have a WebBrowswer control in my application and I can do a SendKeys.Send("^f") to open the Find dialog in the window. This is nifty enough.
What I'd like to do is populate that textbox widget on the Find dialog with a string of my choosing, but frankly I'm not sure where to start on this. As I've got the text - via some processing in my application that is likely the text the user will want to search for, I'd like to populate it without having the user fat finger it in.
Any ideas?
Thanks much,
Matt

So, I solved it myself.
Clipboard.SetText(theTextString);
will set the desired text in the clipboard. The somewhat cheesy solution for the paste was to do:
timer1.Start();
and in the time1_Tick handler, do:
SendKeys.Send("^v");
Not necessarily elegant, but it did the trick.

Controls and .DLL's don't get their own configuration files. As the name suggests, they're Application configuration files, not component. You're control will have to rely on the developer supplying the configuration in his/her application's app.config file if you want to use the .NET Frameworks built-in classes and methods for retrieving config options.
The only way to supply a seperate config file for your component (not a good idea BTW!), is to implement your own config file (preferrably in XML,) specifying your own schema and writing the code to find and load the config file yourself.

Hello,
I have seen datagrid, a view control in Framework 1.0/1.1 but in Framework2.0 datagird also there but little change from datagrid to gridview but no separate view control. Is Gridview control composite of datagrid and a view control. What is there that we can do with gridview but not with datagrid? Is there any major difference. Moroever, what is better to use in the future applications that can provide a full control over gridview or datagrid controls as well as total control on their functionality.
Thanks for answering in advance.

Write the code to do it maybe?
You might want to explain what you want in more detail. This is a very vague question that noone can possibly answer with any kind of accuracy.

Hi, I was wondering if anyone knows a free downloadable forum program. Preferrably in C# and .NET. It would be nice if users had to register before they could post as well.
Thanks

Hi all. I'm using iTextSharp to manage some documents. I want to rotate some pages 180 degrees. I've been reading itextsharp tutorial and about the transformation matrix.
I know that pages without rotation are properly created with:
cb1.AddTemplate(page, 1, 0, 0, 1, 0, 0)
and rotate 180 should be
cb1.AddTemplate(page, -1, 0, 0, 1, 0, 0)
But the page is blank. Maybe is someting about the traslation. Should I put some values in the last two zeros???
Regards,
Diego F.

I have an approach:
cb1.AddTemplate(page, 1.0F, 0, -0, -1.0F, 0, page.Height)
It is rotated, but the text is flipped. I only want to rotate the page, but still readable!!!
Regards,
Diego F.

What a stupid thing!
the solution is cb1.AddTemplate(page, -1, 0, 0, -1, page.Width, page.Heigth)
The trick was the translation. I tried that, but without page.Width.

Diego F.

Hello,
I created a C# console application (without GUI) that scrapes information from webpages. This application runs everyday on a unattended computer with Win2003 SP3, including latest security patches and up to date virusscanner, using a scheduled task. It uses the C# System.Windows.Forms.WebBrowser class to navigate the pages.
The application runs fine for weeks but all of a sudden the following error occurs
Win32Exception details: HRESULT=-2147467259 ecode=87 inner=
Failure... System.ComponentModel.Win32Exception: The parameter is incorrect
at System.Windows.Forms.NativeWindow.WindowClass.RegisterClass()
at System.Windows.Forms.NativeWindow.WindowClass.Create(String className, Int32 classStyle)
at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp)
at System.Windows.Forms.Control.CreateHandle()
at System.Windows.Forms.Application.MarshalingControl..ctor()
at System.Windows.Forms.Application.ThreadContext.get_MarshalingControl()
at System.Windows.Forms.WindowsFormsSynchronizationContext..ctor()
at System.Windows.Forms.WindowsFormsSynchronizationContext.InstallIfNeeded()
at System.Windows.Forms.Control..ctor(Boolean autoInstallSyncContext)
at System.Windows.Forms.WebBrowserBase..ctor(String clsidString)
at System.Windows.Forms.WebBrowser..ctor()
at MyNamespace.Scraper.Scrape()
An important code snippet:
public class Scraper
{
private WebBrowser browser;
public void Scrape()
{
using (browser = new WebBrowser())
{
NaviateToPage(browser);
ScrapeContent(browser);
}
}
}
The application is started every hour. It will run OK for days, until the exception occurs. When the exception occurs it keeps occuring. BUT when a user logs into the system and opens a browser and closes it again. The system runs fine for a couple of days again, until the exception shows up again (from that point on it will continue to fail again until somebody logs on... etc).
The exception is "The parameter is incorrect", but because I don't provide any parameters I don't have a clue which parameter might be incorrect and why.
I examed internet explorer settings on the machine and even scanned the registry for strange settings, but couldn't find anything that could point me in the right direction.
I also looked at the running processes. I examined which processes are running when the problem occurs and when the system is running fine, but there are not differences.
I am a kind of desparately looking for good ideas or background info that can point me in the right direction.
Thanx!
Paul

Hi,
the WebBrowser documentation states:
The WebBrowser control is resource-intensive. Be sure to call the Dispose method when you are finished using the control to ensure that all resources are released in a timely fashion. You must call the Dispose method on the same thread that attached the events, which should always be the message or user-interface (UI) thread.
And:
The WebBrowser class can only be used in threads set to single thread apartment (STA) mode. To use this class, ensure that your Main method is marked with the STAThreadAttribute attribute.
Your code uses the using statement, so Dispose is called.
The other requirements need to be verified.
The exception is an inner exception; ecode=87 means invalid parameter,
and HRESULT=-2147467259 corresponds to hex 80004005 which inside good old winerror.h
is the value for the symbols ERROR_REC_NON_EXISTENT as well as E_FAIL. so that
seems not to help us.
One guess is each new WebBrowser creates a new class name, and somehow these class
names suddenly are not valid any more. Suggestion: count and log each new WebBrowser
and try to recognize a pattern in the failures.
Another idea is something runs out, e.g. disk space for temporary internet files;
you might try to see if something like that occurs, and can be remedied without
launching IE, just to see if your app resumes normal operation.
Hope this helps.
