Font file...
Sorry I don't understand how I should use that...

May sound stupid, but:
Does the font you are using for display have those characters?
If you are using a different encoding, you should get wrong characters, not just question-marks.
Lets say you have a file with ÄäÖö in it. With a wrong encoding, you should get something like JWpM, since there are different chars there. With a wrong font, you will get like "Box","Box","Box","Box" or ????. Windows sees that there is no character in the font for the keycode given and then prints its "standard"-missing-char-in-font symbol.
Try different "standard" fonts (those who come with windows), like "Arial Unicode", "Times", "Verdana", "Arial" ...
Cheers,
Sebastian

The file is only a simple txt-file written in Notepad.
I'm writing the text back to a txt-file and eaven to the Console and error appears there too.
I've tried The UTF8Encoding and then the , å, ä, ö doesn't appear at all.

Hi,
If the file was created on a windows system it is likely that it uses windows encoding.
Try the windows-1252 encoding. This works for german pretty well...

You need to know which encoding was used for these letters. It will probably be Windows-1252[^]. The default for StreamReader is UTF-8.
Check a binary view of the file (you can use the arrow to the right of the Open button in VS, select Open With..., then choose Binary Editor) to see what the values of those characters are. If it's 1252, å should be 0xE5 (229), ä should be 0xE4 (228) and ö should be 0xF6 (246). However, it could conceivably be an old DOS/OEM codepage, in which case it's likely to be either 437[^] or 850[^]. In both of these, å = 0x86 (134), ä = 0x84 (132), and ö = 0x94 (148).
If it's something more obscure you may be able to find it at FileFormat.Info[^]. Input the Unicode value of the characters (the hex values I've given for 1252).
When you've worked out what code page you're dealing with, use the following:
StreamReader sr =
new StreamReader(
file,
System.Text.Encoding.GetEncoding(1252)
);Replace 1252 with the correct code page number.
Stability. What an interesting concept. -- Chris Maunder

I am working on a database application that I call MultiBase. The jist of the application is that it will load a database and create a GUI to interact with it. The application also impliments search and reporting capabilities. The application is currently a winform application, but I plan on implimenting a web interface at a later date.
Currently when I select the database to use my application looks for an associated XML file that defines the controls, associated database fields, etc, to be used to create the GUI. The XML looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<MultiBase xmlns="http://tempuri.org/MultiBase.xsd">
<control>
<controlType>ComboBox</controlType>
<displayText>Manufacture</displayText>
<databaseField>Manufacture</databaseField>
<databaseLookUp>Manufactures</databaseLookUp>
<displayGroup>1</displayGroup>
<displaySubGroup>1</displaySubGroup>
<tabIndex>1</tabIndex>
<toolTip>Select/Enter a manufacturer</toolTip>
</control>
<control>
<controlType>TextBox</controlType>
<displayText>Part Number</displayText>
<databaseField>Part_Number</databaseField>
<databaseLookUp></databaseLookUp>
<displayGroup>1</displayGroup>
<displaySubGroup>2</displaySubGroup>
<tabIndex>2</tabIndex>
<toolTip>Enter part number</toolTip>
</control>
</MultiBase>
In addition to storing the controls to be used in the GUI I want to store the reports that the user has created. The XML would look something like this:
<report>
<reportName>All Records</reportName>
<selectCommand>select * from main</selectCommand>
</report>
Would it be possible (or correct) to store both the controls and the reports in the same XML file (and how do I do that) or use a seperate file for the controls and reports (which would be easy)? I was trying to keep the extra files to a minimum. I would like to have one XML file store both the controls and reports, but I'm unsure as to how to setup the layout and then use the the XmlDocument object to iterate through it (and still keep a well formed document). There is no relation between the controls and reports.
Any thoughts?
Thanks.

You can try some thing like this...
<?xml version="1.0" encoding="utf-8" ?>
<MultiBase xmlns="http://tempuri.org/MultiBase.xsd">
<controls>
<control>
<controlType>ComboBox</controlType>
<displayText>Manufacture</displayText>
<databaseField>Manufacture</databaseField>
<databaseLookUp>Manufactures</databaseLookUp>
<displayGroup>1</displayGroup>
<displaySubGroup>1</displaySubGroup>
<tabIndex>1</tabIndex>
<toolTip>Select/Enter a manufacturer</toolTip>
</control>
<control>
<controlType>TextBox</controlType>
<displayText>Part Number</displayText>
<databaseField>Part_Number</databaseField>
<databaseLookUp></databaseLookUp>
<displayGroup>1</displayGroup>
<displaySubGroup>2</displaySubGroup>
<tabIndex>2</tabIndex>
<toolTip>Enter part number</toolTip>
</control>
</controls>
<reports>
<report>
<reportName>All Records</reportName>
<selectCommand>select * from main</selectCommand>
</report>
</reports>
</MultiBase>
This gives more flexibility, in that you can associate one or more reports to a single form/database...
Hope this helps!!!

Have you seen MyXaml[^]? It does xml object graph instantiation (declarative programming) for generating GUI's, etc., and as a general reflection instantiator, you can create your own classes to support your reporting needs in the same xml file.

I am working on a database application that I call MultiBase. The jist of the application is that it will load a database and create a GUI to interact with it. The application also impliments search and reporting capabilities. The application is currently a winform application, but I plan on implimenting a web interface at a later date.
I have started writing a DLL to handle the database access. I'm lost as to if I want my DLL to return a dataset and then have a seperate class (? business logic ?) handle the bindings (and currency manager) or if I want to just return a datarow and somehow bind that to my winforms controls (don't think I can bind a datarow to a control, I would have to come up with some other way).
So my question is: In implimenting a n-tier (or 3 tier) applicaion what is the best way to present the data from the data tier to the presentation tier (via the business logic tier ?) ?
I'm thinking of returning a dataset to my record class (that handles the bindings and currency manager) If a new record is added, then send the dataset back to the data tier via the record class (which I would call my business logic).
Any thoughts?

Hai,
I am having an application with vb.net.But for some functionality(since the drawbacks of vb)I need to use c#. Is it possible to use c# in vb.net project.
If possible How I can include, and can I debug the project directly(Seperate compilation required?)?.
I am sure ,some body can advice me with details and that will be very helpful for me.
Thank you,
Rahul

*grin* I'm not touching this.....
You need to create a C# class library, which you can then import as a reference in your VB.NET project, and then you can import the C# projects namespaces and call it's methods. This will mean you will ship with a dll containing the C# code. If you want to move your entire project to C#, there are some excellent VB.NET -> C# converters available.

hai Christian Graus,
Thanks much.I will try that way.One more doubt I am having,How to create a class library in C# for a particular class?
Thank you.
Rahul.

A class library is a project that compiles to a dll and has no entry point ( no static void main ). You can put any classes in there that you like.

Im interested to know what you think can only be done in C# that cant be done in VB.NET - they are essentially the same language with a different syntax.

Really? VB.NET doesn't support "unsafe" or pointers. But, when there's will, there's a way...

Wrong - C# has pointers, overloaded operators, etc. On the other hand, VB.NET apparently has optional parameters.

How these two function saperate and run for voice. Which of these functions parameter use for voice.
The two functions are:
1: int ISampleGrabberCB.BufferCB(double SampleTime, IntPtr pBuffer, int BufferLen )
2: int ISampleGrabberCB.SampleCB( double SampleTime, IMediaSample pSample )

What are you trying to do exactly ? What SDK did these API calls come from ?

How In this function voice run "int ISampleGrabberCB.SampleCB( double SampleTime, IMediaSample pSample )" .
And how it can be saperated for voice.

Hey everybody I get this error on my program only when I put a picture on it. Can anyone tell me why this is happening? The second I put one picture on it crashes.
//
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dll

Hi!
What do you mean by "I put a picture on it"?
In a designer? Drop an image on your application? Anything else?
What else can you "put on" your program to make it not crash?
