The example is right, but the concept being encouraged is not.

There should be commands that launch the forms in this case, and how it is called shouldn't be hard coded beyond the minimum. The command class allows for a short cut key to be associated and that should provide the nescessary access. Overriding the keybouard handler is really too low level for what is already provided by the framework.

Panic, Chaos, Destruction.

In the MDI form, create a menu item for each child form and assign keyboard shortcuts to the items.

Hey,
This has gone on long enough. What people are trying to tell you is to just assign a function key as a short cut key. These assignments are usually done through the designer but example code is

this.MyMenuItem.ShortcutKeys = System.Windows.Forms.Keys.F1; .

Alan.

Please try out something on your own before posting so many questions. You can assign function keys as shortcut keys for menu items in the form designer. Select the menu item in the designer and look for the Shortcut property in the Property Explorer window.

MS provides Speech SDK. This should let you do all this. Here[^] is an article that you can refer.

Thank you for your reply
I go through it but when i run my application it starts vista speech recognition engine.So whatever i speak related to my own grammar it does not respond me.
I have use another example but it gives me error on LoadGrammer() say "the language for the grammar does not match the language of the speech recognizer."

here is my code:

SpeechRecognitionEngine rec = new SpeechRecognitionEngine();
            rec.SetInputToDefaultAudioDevice();
            Grammar gram = CreateCustomGrammar();
            rec.UnloadAllGrammars();
            rec.LoadGrammar(gram);
            rec.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(rec_SpeechRecognized);
void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            MessageBox.Show(e.Result.Text);
        }

Tell me where i am getting wrong.
Thank you.

Use report viewer from a text file?

CelestialCoder22-Nov-09 20:19

Hai,

I need to generate a simple report.
No data base or nothing, just a text file read from a USB device.(Only 72 records.)
When I click a button the text file should be read and values shown in a tabular form of my choice. Some calculation also involved.

I am planning to use Microsoft report viewer. It needs a dataset or a class at least.(I am new to databases! please forgive if my terminology is wrong!.)
Since I have no data elements that needs to be updated ,I think I don't need a live database type connectivity. Just populate and wait until close or next load.(Print may be needed).

Please suggest a suitable method with possible details.

Thanks for the time.

With Regards
Roy Thomas

Use StreamReader() or similar functions to read your textfile and break it down to its constituent parts. These items can then be used to poulate a DataSet which you can pass to report viewer.

I am creating a dataset like this
.....
MyDataTable.Rows.Add(1, "AS","test1");
MyDataTable.Rows.Add(2, "BD","test2");
....
Here I am adding all three colums in a row by this method.

Suppose I need to add only 3rd colum in second row. How is the method?

Thanks

A data table does not have different schemas for each row; it has *one* schema for all the rows. So you create all the columns you need and add them to DataTable.Columns, letting some columns be null for some rows.

I don't know Microsoft Report Viewer, but whatever UI you use to present the data is where you'll grapple with layout - not in the data structure itself.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
