Are you talking the desktop browser or a browser in your own application?
If you mean in you own application, the way to prevent GoBack() from everworking would be to clear your browser object's history after each navigate completes. Unfortunately I haven't found a way to do that and I can't find any codeproject articles or when searching MSDN, searching with Google and searching with MSN search that explain how to do it.
My quick and dirty suggestion would be to not implement/expose that functionality by leaving off the "back" button in your application. Additionally, since you cannot go back, it would make no sense to implement a "forward" button either. Unfortunately that leaves open the possibility that the user will use the backspace button while the focus is on the browser window and not in an editable field which would most likely cause a GoBack() to occur.
Sorry, best I can do for you.

Hi!
I don't even know if this is possible or not...
I have an (3rd Party) application, that writes text into a logfile. I want to intercept this filestream an handle it in my own application. Is it possible (and how is it possible?) to redirect the stream into my application (or to get a copy of it)? I suppose that I have to use some win32-Api functions to achieve this.
Any help is appreceated 
Thanks
Dirk

thanks a ton in advance
how should we add for value members and display members if binding is through the datareader and not dataset
currently i add using a loop due to which i cannot set the value memebers and display members had i done that using datasets
ComboBox1.Items.Clear()
If (dr !=null)
{
while (dr.Read())
{
ComboBox1.Items.Add(dr"Name"]);
}
}
The secret of gettting ahead is getting started

|
|
Why don't you use the datareader to populate the dataset?
|
|
|
|

thanks paul,
what you suggested can be done , But Just wanted to know if using datareader directly against combobox and setting value members and display members is possible ..
and again
if i am using datareader to fill the dataset against dataadapter , what difference in the performance will it make (please consider this query to be on lower priority;))
please tell if some work around is possible ..

Hi All,
My app is MTA, because it needs to be for directshow. I'm now wanting to use OpenFileDialog, but it seems to not work: calling ShowDialog results in a ThreadStateException with additional information
"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process"
Anyone got any ideas for an alternative or a workaround? My main thread needs to stay MTA, or directshow stuff i'm doing will not work.
Any help greatly appreciated!

Hello
Why don't you make another STA thread, and show the openfile dialog within it?
|
|
|
|
|
Problem with that is that if i show the dialog from another thread then i can do one of two things with my UI thread:- either Join on the worker thread (which locks the UI to the extent that it won't even redraw), or i can use a callback/message/event and invoke the dialog asyncronously - but then the main app's UI will be active because the dialog won't be modal.

Well, I anticipated this, but I believe the solution is simple.
1- Make a bool value that is always false
2- At each UI event (click, highlight, etc...) you check that value, if it's false continue
3- When you show the openfileDialog -or just any other dialog- you set this value to true and create and object reference to that dialog (of type Control maybe)
4- When the dialog returns, you set it to false again -so that the UI will work again-, then process the data returned by that dialog
In the Focus event -when the user set the focus to your main Application- check if the object reference is null, if not call its Control.Focus();
This way when the user clicks or moves the mouse around you'll still be able to draw your UI, yet the user won't be able to use it until the dialog returns. Also he won't be able to change focus until the dialog return.
I know it's a bit lousy way, but that is what I can think of.
I hope it works

Hi Guru's
I recently moved from C++ to C# and so far, so good! But I do seem to have a little problem with displaying my reports designed with our good friend crystal reports! I am writing a simple Point Of Sale application for one of our clients, but I can't seem te send the reportviewer a SQL or "Format" string.
When the user selects the report he/she wants to see, I pop up a little dialog with a list that displays some invoice numbers. The user selects the invoice number and click on the "Print" button... and it displays the report... Brilliant!!  BUT... with ALL the entries in my table! 
How do I pass the invoice number to the report and have it display all entries of the selected invoice number only? In C++ I used to, grab the values from my little dialog, construct a SQL statement using those values, pass it to my report and display it! I am almost sure one should be able to do the same in C#. 
Can anybody help me with this please!?
Many, MANY thanx!

You have an option in the report to set parameters. You can set a parameter and then you can send the parameter from the dialog box.
You could write a function like this
<br />
private ParameterField AddParameter (string paramName, string paramValue)<br />
{ <br />
ParameterField paramField= new ParameterField();<br />
ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue ();<br />
ParameterValues paramValues = new ParameterValues ();<br />
paramField.ParameterFieldName = paramName; <br />
paramDiscreteValue.Value = paramValue;<br />
paramValues.Add (paramDiscreteValue);<br />
paramField.CurrentValues = paramValues;<br />
<br />
return paramField;<br />
}<br />
And to add a parameter
<br />
private CrystalDecisions.Windows.Forms.CrystalReportViewer crResults;<br />
crResults = new CrystalDecisions.Windows.Forms.CrystalReportViewer();<br />
<br />
rptMyReport crReportDocument = new rptMyReport();<br />
crResults.ReportSource = crReportDocument;<br />
<br />
CrystalDecisions.Shared.ParameterFields paramFields = crResults.ParameterFieldInfo; <br />
paramFields.Add(AddParameter("paramName",strValue)); <br />

Hi Tarakeshwar!
In future I promise to write a little article on the subject and I will be sure to put your name all over the place. I will also do all future communication via the forums for all to see. Sorry about that my fellow gurus! 
I made the requested changes and and the "report.Load(strReportPath);" seems to be working now.
But I am still having a problem with the line "paramFields.Add(AddParameter(PARAMETER, strTransactNo));" When I run the application it states that "Object reference not set to an instance of an object".
