Hi,
I'm using Webbrowser control with .NET 2.0, Can you tell me how I can autosave the web page after navigation successful?

Write an event handler for the WebBrowser.DocumentCompleted event that accesses the document content via the WebBrowser.Document, WebBrowser.DocumentText or WebBrowser.DocumentStream property and uses one of the return values to save the document.

I have saved DocumentText into a file, but when loading this file using web browser, the webpages' images disappear.
How can I auto_save the web page as the SaveAs function of WebBrowser?
Thanks,
Hung.

I'm afraid there is no build-in support for this (at least not without user interaction). The HtmlDocument instance returned by the WebBrowser.Document property exposes an Images property that returns a collcetion of all image tags of the document. Retrieve the image URLs (shown in the documentation of the HtmlDocument.Images property), download them by using a child of the WebRequest class and then finally save them.

I am doing following to run a remote-machine's process on that remote-machine:
ConnectionOptions objConnectionOptions = new ConnectionOptions();
objConnectionOptions.Impersonation = ImpersonationLevel.Impersonate;
objConnectionOptions.EnablePrivileges = true;
objConnectionOptions.Username = strUserName;
objConnectionOptions.Password = strPassword;
ManagementScope objManagementScope = new ManagementScope(@"\\remote-machine-name\ROOT\CIMV2", objConnectionOptions);
objManagementScope.Connect();
ManagementClass processClassFinal = new ManagementClass(objManagementScope, new ManagementPath("Win32_Process"), null);
ManagementBaseObject inParamsFinal = processClassFinal.GetMethodParameters("Create");
inParamsFinal["CommandLine"] = @"\\remote-machine-name\some-directory\someProgram.exe";
ManagementBaseObject outParamsFinal = processClassFinal.InvokeMethod("Create", inParamsFinal, null);
But for some reason it does not work and I don't know why???????
outParamsFinal["processId"] returns null, instead of a valid processId.
Is there any one who could help me in that..............
Thanks

Perhaps a review of the Win32_Process.Create[^] are in order:
The Create WMI class method creates a new process. A fully-qualified path must be specified in cases where the program to be launched is not in the search path of Winmgmt.exe. If the newly created process attempts to interact with objects on the target system without the appropriate access privileges, it is terminated without notification to this method.
For security reasons the Win32_Process.Create method cannot be used to start an interactive process remotely.

So... What exactly I am going to have to do in order to achieve my goal????

PSEXEC[^]. But, the down side is that most virus scanning software considers this app to be an "unwanted" .exe. If the virus scanner sees it and doesn't like it, the scanner will stop PSEXEC from running.

Hello All ,
I am Again taking your Time for same problem but in reverse format

The code would be something like:
DateTime dt;
DateTime.TryParse(YourSTringHere,dt);
textbox.Text = dt.ToString("dd/MM/yyyy");
Hope that helps.

the DateTime class has a Parse() method and a ToString() method to convert from and to
a string; both accept an IFormatProvider to specify the format, so you can do all
kinds of conversions, whatever you want.
You must make sure the format used to store/persist the datetime is fixed (hence you
really should always specify a constant IFormatProvider), so it
works independent of your System's regional settings; if you fail to do so, your database
or file will not work on some other machines.
You have had all of this on your earlier questions. I dont understand why you ask again.

Good Day Sir/Maam,
I'm here to inquire about the name of the IO Exception thrown when I tried to write to a certain location (EX: Drive A and the Drive is already full.
Tried searching on google, but came up with nothing valuable.
Thank you in Advance, Good Day.

If you are using .net 2.0 there is a DriveInfo class that you can use.
Here is a MSDN link:
ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEVFX.v20.en/cpref8/html/T_System_IO_DriveInfo.htm

Sir, Im using File.Copy to copy a file, is there an exemption thrown if the "location" im writing is at full capacity?
|
|
|
|
|
Most likely you would get an IOException. I don't know for sure since I haven't tried it. I think it would probably be a better idea to use the driveinfo class to check you drive and figure out how much space is left before you try to copy the file.

after i made my website and aspx pages
and i upload the website
i recive this error
Server Error in '/' Application.
-----------------------------------------------------------------------------
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>

so can any one solve this problem
or tell me how to solve it
thanks all

Change the web.config as suggested, or if you're able, get onto the box (ie using terminal services or similar) then when you run the application it'll give you the stack trace which should help you locate the error.
.NET hides the full details by default unless you're running it on the box where the web application is hosted.

Hi,
On internet, i see everyone said : "If you are not sure which port is available, you can use 0 and server will search automatically for available port", but i doubt how could client call method on server when client don't know server's port?
Example :
On Server
ChannelServices.RegisterChannel(new TcpServerChannel(0));
On Client
MyClass obj = (MyClass)Activator.GetObject(typeof(MyClass),"tcp://localhost:?/Hello");
What number could i put in "?" ?

Buttons don't have return values.
(new Random()).NextDouble(); will give you a random number between 0 and 1, inclusive.
