I mean that other colors appear instead of the ones that were supost to.. and the contours are smudged... the really strange thing is, that if i keep the debug folder opened the picture displays correctlky (it's a picture on a form that loads on startup

I think you specified the value of the picturebox image at design time. Instead of that, load and set your image at run time. this will retain the quality.

OK Now, supose i don't want anybody to be able to mofify my picture, what should i do? Hope i'm not bugging you too much

Rename .jpg to .dll ..!!!! Just kidding!!
You can embed the image as a project resource by making image part of the project and extract the image just as you were accessing file.
System.Reflection.Assembly asm = GetType().Assembly;
StreamReader stream = new StreamReader(asm.GetManifestResourceStream("FULLY_QUALIFIED_NAMESPACE.FileName.jpg"));

Thank you very much . Hope I'll get it right( )) )

 i still can't make that picturebox look good... i managed to embed it, and now i set it's value at run-time.. pls help
|
|
|
|
|
Huh .. strange .. is it a very large or a high-DPI picture? I can certainly give it a try if you dont mind uploading the image.

Hi,
I'm very new to the C# application development architecture. What I am trying to accomplish is a class-system that looks a lot like the class system C++ is providing. An example of this architecture would be something like earth - an environment with animals and plants. Animals feeds the plants, and the plants lets the animals spread their seeds. They need eachother in order to function properly. What they need as well though, is a base - somewhere to walk. This is where "an Earth" come in to the picture. Earth sends parameters to the plants and animals, which handles the parameters, does what they have to do, and returns the result to earth - which continues sending requests and demands.
This is it.
I want an application where I might converse between classes without sending them as attributes all the time. Right now I'm having abstract classes which handles requests and demands from the Main Form and returns the result. It's very clumsy, since I have to send all fields that is beeing worked with as a parameter to the static function.
Is it somehow possible to set important fields to absolutly public? Or am I fishing in the wrong waters - are my idea of the optimal architecture incorrect?
I appreciate all answers I'll get. Thank you in advance,
// Leo

Having everything public is NOT good architecture....
First the bad news - stuff C++ does that you can't do here. Two things spring to mind - no multiple inheritance and no friend classes.
You simulate multiple inheritance through interfaces, you can have a base class and impliment as many interfaces as you like. I find when I use C++ now, I tend to create classes to mimic the interface concept, it's not so bad.
No friend classes is a PITA though. There's really no way around this that I can see.

The good news is that you have delegates to send messages between classes now, which come in very handy, very often. You should look into using them to define communication between classes.

I have an application that I need to verify local user accounts against. I'm having a hell of a time finding information on this. I have found that the local windows account passwords are encrypted and I've got some direction on the cypher, but nothing on how to access it. So for example, I have accounts Admin, Ed and Erin. If someone tries to login as admin I need to verify their password against the local machine admin account. Any suggestions? Thanks.

Hello, I am developing an application that uses SqlServer and Crystal Reports, and I'm having some trouble when deploying the application. Because the sql servers on my development machine and in the client machine have different names.
So I created an app.config file, and saved there the name of the server. For non-crystal reports operation everything is fine, I just have to change the name of the server in the app.config, but how can I dinamically change the name of the server for a crystal report .
Thanks in advance for any answers.

Use one dataset for creating the crystal report.
// connection string from app.config file
con.ConnectionString=c.g_strConnection;
// filling the dataset
adapt.Fill(dsBatch);
// creating an object of the crystalreport
crBatchSummary crObj=new crBatchSummary();
crObj.PrintOptions.PaperOrientation=PaperOrientation.Landscape;
crObj.PrintOptions.PaperSize=CrystalDecisions.Shared.PaperSize.PaperA4;
// setting the datasource of the crystal report
crObj.SetDataSource(dsBatch);
// Assigning crystal report object to the crystalreportviewer
crvBatch.ReportSource=crObj;

Hi
In design time , create the Dataadapter & dataset.
Then create a new Crystal report and select the datasource as
projectdata -> ADO Datasets -> Dataset name.
Then all the columns will appear in the field list and you can design the report.
In code behind file , write the codes mentioned before.
hope this will clarify ur doubt..

I'm putting together my first C# database application. It compiles fine and seems to be connecting to my database fine, but when I create the command I get the following error:
An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll
This is the line VS claims is causing the error:
this.cmdGetNewClients = new System.Data.OleDb.OleDbCommand();
The code around it is:
this.cn.Open();
this.cmdGetNewClients = new System.Data.OleDb.OleDbCommand();
cmdGetNewClients.CommandText = @"SELECT ClientName FROM Clients";
cmdGetNewClients.Connection = this.cn;
OleDbDataReader rdr = cmdGetNewClients.ExecuteReader();
while(rdr.Read())
newClients.Add(rdr["[Client Name]"]);
rdr.Close();
cn.Close();
Can anyone tellme why I'm getting this error and how to fix it?\
Thanks!
The ends can never justify the means. It is the means that determine the ends.

The error is too general. Wrap the code in a try catch block and see what the true error is.
If you catch and exception of type SqlException you can try this:
foreach(SqlError err in sqlEx.Errors)
Console.Writeline(e.Message);
Otherwise just check the InnerException. It could be something simple like a login issue.

Thanks for the advice, can you give me a hand writing the try/catch though? I'm afraid I'm a bit new to C# and rusty in the other stuff I knew in college.
it would go something like this:
try
{
this.cmdGetNewClients = new System.Data.OleDb.OleDbCommand();
}
catch()
{
foreach(SqlError err in sqlEx.Errors)
console.WriteLine(e.Message);
}
What goes in the catch()?
Thanks so much for helping.

Try something like this:
try
{
//insert your code here
}
catch(OleDbException ex)
{
Console.WriteLine("Message: " + ex.Message + "\n");
if(ex.InnerException != null)
Console.WriteLine("Message: " + ex.InnerException.Message + "\n");
foreach(OleDbError e in ex.Errors)
Console.WriteLine(e.Message + "\n");
}
