This is obviously a class of your own design, is there some reason why you'd need to do both, that is, why you'd need to call the constructor for every item in the array ?

If I understand you correctly, then no i don't believe there is a reason, but that just happens to be the way i figured out how to make "Object reference not set to an instance of an object" go away. I didn't think i would have to do both either, but if i don't "Object reference not set to an instance of an object" pops up on everyone of the classes..uh..objects?.

And about the second problem, i have taken the (int)Sprite.BlueBlob out and replaced it with a ZERO like it should be, but it does the same thing. "Value does not fall within the expected range" when i try to create a surface.

...help..me... Cry | :((

Then it must be something wrong with the data being passed in to the method. Look at the parameters you're passing in to the constructor, and then read MSDN to see what the valid ranges of values are that you can pass in.

I FINALLY figured it out.

When i entered this:

SpriteSet[(int)Sprite.BlueBlob].SpriteSurface = new Surface(SpriteSet[(int)Sprite.BlueBlob].FilePath, description, display);<br />

SpriteSet[(int)Sprite.BlueBlob].FilePath was equal to Application.StartupPath + "\\Blob_Sequence.bmp"

Unfortuantely Blob_Sequence.bmp is not the name of my file.. its BlueBlob_Sequence.bmp.

I never would have guessed that, that would give me that kind of error.

thanks for your help!

ugh.. my brain hurts...but in a good way... i think? Laugh | :laugh:

Yeah, that's a totally dumb error to return. Why not 'file does not exist' ?

Hey everybody!

I wondered if it is possible to use windows' auto-complete.
I don't mind if it'll be using web application or not.

we all know the option of "remember my password" in mail accounts and many other places, and the listbox that opens under textbox with old texts that the user entered.

is there a way to use that database in c# win application or c# web application?

if there is can someone help me with that (tutorial, or somekind of explanation).

Thanks Alot!!!

Good afternoon:
Have you ever used SMS
Systems Management Server?

If you have then you know you can connect to another PC and interact with the Desktop.

I would like to know how this is done and are there any good articles?
I have looked under Video Buffer, Video Stream but just cant find what I am looking for.

Thank you very much,

Looking for MS Word AutoShape like Toolbar

Tried using ContextMenu and ToolBar controls, utilizing ownerdrawn = true to render a matrix of shape icons in-place-of the owner drawn MenuItem.

The problem is there is no way to correlate the mouse click coords to that of item selected in the ownerdrawn MenuItem.

Looking for some sample code in which someone has attempted to create an MS Word AutoShape "like" control.

Thanks

Hi all,
I am trying to connect to an ACCESS database and read data from it. I believe the connection opens and closes fine, but when I add the line to Read from the data (ExecuteReader) I get the following exception error:

[An unhandled exception of type 'Microsoft.Data.Odbc.OdbcException' occurred in microsoft.data.odbc.dll]

I also downloaded and installed the latest MDAC and the ODBC driver (unless there is other stuff to be installed I am not aware of!)
And it is not an SQL-command error because (and this is also interesting) when I copy the table to my C: drive, everything works fine and I get the results I am looking for, even though it is pointing to the I: drive (the local server where the data is stored)

////////////here is the code:
string connection= "Driver={Microsoft Access Driver (*.mdb)};"
+ "Dbq=I:\\ACCESS2000\\US_MASPS.mdb;" ;

OdbcConnection myConnection = new OdbcConnection(connection);
myConnection2.Open();

string select = "SELECT * from US_MASPS.TBLGMS"
+" WHERE SeqNo = 12";

OdbcCommand aCommand = new OdbcCommand(select, myConnection);
OdbcDataReader aReader = aCommand.ExecuteReader();
/////////////

Thanks in advance

I would recommend moving from a DBQ connection string to the following:
Standard security:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;User Id=admin;Password=;"

Workgroup (system database):
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;Jet OLEDB:System Database=system.mdw;"

With password:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;Jet OLEDB:Database Password=MyDbPassword;"

Also check out www.connectionstrings.com

Thanks for the reply. I know that website! It is where I got the connection string from.

But I found the solution.. simply, the path must be added to SQL statment!!!

Thanks for the hint though!

I need to develop a client-based component (similar to activex, but using .NET) that can be used in web pages just like an activex control can. Is this possible? I have done several searches but can't seem to find exactly what I'm looking for. Thank you.

ProcessStartInfo.Arguments - No Spaces in Path?

pgaribay521131-May-05 6:46

Process p = new Process();
p.StartInfo.FileName = "wordpad.exe";
p.StartInfo.Arguments = @"C:\My Dir\My file.txt";
p.Start();

Wordpad launches successfully then I get the error message that "Cannot find file C:\My". So it looks like my path is being treated as 3 separate arguments (space delimited). How do I specify an argument that has spaces in the path or file name?

Re: ProcessStartInfo.Arguments - No Spaces in Path?

It's easy:

Process p = new Process();
p.StartInfo.FileName = "wordpad.exe";
p.StartInfo.Arguments = @"""C:\My Dir\My file.txt""";
p.Start();

Re: ProcessStartInfo.Arguments - No Spaces in Path?

If command line arguments contain spaces, they need to be wrapped within doublequotes. So

p.StartInfo.Arguments = @"""C:\My Dir\My file.txt""";

will work.

identifying Partial type by using reflecton

Hi friends,
In VS 2005 a new partial type is introduced. Have you know how we can identify a type is partial or not by using reflection in c#. Please help..........

Wink | ;)

Rathish P S

I thought partial types was a compilation thing only? The compiler patches together all partial types with the same name and generates one single IL class, I think.

Hi,

I'm trying to use TypeConverters on a a property which is an Array of specific objects.
It works well converting to a string, but fails to convert back to the obejct.

I have tried setting up my own Typeconverter but its methods are never called.

Any ideas on what I need to do to get this working.

You don't need API to do that.
If the file and the application in the machine, you just need this:

<br />
System.Diagnostics.Process p=new System.Diagnostics.Process();<br />
p.StartInfo.FileName="C:\\a.jpg";<br />
p.Start();	<br />
<br />
//this code open default jpg browser, and open c:\a.jpg in it.<br />

I hope that's you need to.
