Re: Can't paste a image to PicBox Heath Stewart3-Dec-03 8:16 Heath Stewart 3-Dec-03 8:16  I don't know off the top of my head, but copying a JPG file may not use the DataFormats.Bitmap clipboard format. The best thing I can tell you is to set a breakpoint at your condition and debug your app to see what formats are there. You can also use ClipSpy[^] to also see what formats are being used. What exactly are you copying this file from? If you're doing it in your own program, make sure you copy the data into the DataObject the same way and using the same clipboard format as you do when you retrieve it.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

I only want to paste/drag&drop to my program, and the books make it look so easy they all seem to be the same code I pasted in my first message - so I'm not sure what I'm doing wrong. Re: Can't paste a image to PicBox Heath Stewart4-Dec-03 5:07 Heath Stewart 4-Dec-03 5:07  The only thing you seem to be doing wrong is using the wrote clipboard format. Be sure to copy a JPEG from Windows Explorer into the clipboard, then examine it with ClipSpy to see what formats are there. If DataFormats doesn't have the string you need represented, just pass the string itself - that's all that it is). If nothing else, read the sections of the Windows Shell documentation in the Platform SDK that deal with the clipboard, dragging and dropping, and clipboard formats. I did many many years ago and I'm glad I did.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Thanks again - C# MIME parser pahlsson3-Dec-03 0:53 pahlsson 3-Dec-03 0:53  I'm currently writing a C# MIME parser and a problem has occured, encoding I've written a hack that converts iso-8859-1 to a readable form by taking out the ASCII-value of the characters and then replace the code (for example =E5 is the swedish character 'å') with the corrent character. But today I got a nasty spam with the following text (in the header) that I don't know how to encode: From: =?koi8-r?B?6OhMLfRB6EkgKDk5NS04Mjk0KQ==?= <mc7yfccu@buch.de> The charset is koi8-r, but then? According to another email-client the correct translation is èèL-ôAèI (995-8294) <mc7yfccu@buch.de> Is there a general way of converting strings with known encoding-strings like koi8-r, iso-8859-1 etc? // Niklas Re: C# MIME parser Heath Stewart3-Dec-03 3:46 Heath Stewart 3-Dec-03 3:46  Take a look at Encoding.Convert (and the various encoding-related classes). This converts to/from ASCII, UTF7, UTF8, and Unicode, so any charsets should be able to convert.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Hope I can find the answer... Thanks... Re: create global database connection Braulio Dez3-Dec-03 2:43 Braulio Dez 3-Dec-03 2:43  Hi, you could create an static class, and have a method called "getConnection" from there you can get the connection from anywhere. Just one advice... I would use connection less, instead of single connection, ... just connect to the database when you need it, the .net Framework keeps a pool of connections so no loose of performance when reopening the connection HTH Braulio Re: create global database connection Sean McCormack3-Dec-03 2:51 Sean McCormack 3-Dec-03 2:51  akokini, There's a difference between defining the connection globally, vs. having a global connection. Defining the connection globally is good practice, and can be done either through the .config file, or through a static variable. Having a global connection is VERY bad, since it will destroy your ability to have proper connection pooling, and even worse, could cause serious problems between different classes if they're all using the same connection at the same time. Here's an example of defining the connection through a static variable: using System; using System.Configuration; namespace sean.config { public class Config { public static string DataBaseConnection = @"server=192.168.0.1;Trusted_Connection=false;uid=sa;pwd=;database=Northwind"} } You could then reference it anywhere in your code by doing the following: SqlConnection conn = new SqlConnection(Config.DataBaseConnection) You could take it a step further, and define the connection in a config file. Here's an example: The configuration file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="mydb" value="server=192.168.0.1;Trusted_Connection=false;uid=sa;pwd=;database=Northwind" /> </appSettings> </configuration> The modified config class: using System; using System.Configuration; namespace sean.config { public class Config { public static string DataBaseConnection = @ConfigurationSettings.AppSettings["mydb"]; } I hope that helps!

Good luck Re: Create query for excel Heath Stewart3-Dec-03 3:38 Heath Stewart 3-Dec-03 3:38  Specifically, either using the OLE DB driver for Excel (using the System.Data.OleDb namespace classes), or the ODBC driver for Excel (download ODBC.NET from Microsoft).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

When I set an object to the class [PublicClass myPublicClass = new PublicClass] I get the Compiler Error CS0122 [Class is inaccessible due to its protection level] What seems to be the problem? Any help would be great. Thx Re: PublicClass() is inaccessible due to its protection level Heath Stewart2-Dec-03 20:07 Heath Stewart 2-Dec-03 20:07  A couple things come to mind: While the class is public, the default constructor might not be (or whatever constructor you're using). If you don't specify a default constructor, it is inherited (access modifier and all) from its parent. In your case, System.Object already has a public default constructor so you're class will inherit that unless overridden. You may have a type name clash, and the compiler is choosing one over the other. It usually spits out warnings or errors, but who knows sometimes. Make sure you don't have a similarily named class from another imported namespace Most likely, the problem is #1 above. The documentation for the C# compiler error CS0122 affirms such.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?
