I already tried to create a DateTime Object from
datum
and the Cast worked perfectly, but there occurs the same Exception when I edit the Code as follows:
DataRow[] VerlaufDatum = data1.Verlauf.Select("BehandlungsID=" + BehID + " AND Datum= '" + Convert.ToDateTime(datum) + "'");
I think it has something to do with the '=' Operator, but I don´t know what´s wrong with it

Try by formatting the date and pass this string:
"#" + dt.Month + "/" + dt.Day + "/" + dt.Year + "#"

You need to convert one or both sides of your statement so that they are both the same data type. A string type and a datetime type are incompatible, so find a way to collect the datetime information contained in your string explicitly and use DateTime.Parse to make it compatible.

Also, you should try to format your date as following:
"#" + dt.Month + "/" + dt.Day + "/" + dt.Year + "#"

thanks a lot  ))
that works fine and solves the problem perfectly!

I'm glad, no problem.

Ah, I love being reminded of Jet. Now we know where they DataSet team got there start.
Need custom software developed? I do C# development and consulting all over the United States.
If you don't ask questions the answers won't stand in your way.
Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.

This is more of a theoretical question that anything else. There is no way to simulate it(All results will differ from implementation to implementation) so here goes. What will be faster (The least amout of bytes). To download (Save) a file from a website or to open the file directly in the browser

Well if you download an image or open directly in browser you would still need to stream the image, so the byte count for the image atleast will always be the same. As far as i know whenever an image is viewed in the browser it is downloaded to computer anyway. So surely its the same process.... just my thoughts, i may be wrong
If only MySelf.Visible was more than just a getter...

You're right.
If you save it, the byte stream will go to a place you have to assign. If you open it, you will save the picture in your cache. But if you want to open it I guess you also put it in your RAM, so I guess saving would be slightly quicker.

Thanks... its good to know i get things right sometimes
I was thinking there would be extra work in the loading but as the OP asked about displaying in a browser i assumed the intent was to show it to the end user in which case he would be displaying after download anyway... but as, like in most cases, the OP is AWOL we shall prob never know their aim lol

No, it won't, since there is no telling how big the file is and it could run the system out of memory, the file is written directly to disk, then the file is launched using the Shell.
...and the OP didn't say anything about a picture, but listed generically, "file".

That's true.
And we assume it is a file.
The file has to be downloaded, always, if you save it or if you show it.
But if you show the file, the computer has to write the bits to the screen. This will cost time and possible more data which will stream to the ram.

There's no difference between the two processes. The file is downloaded into the browser cache either way.

Hi,
save=download+writeToFile
open=download+writeToScreen
Now what is faster depends on the complexity of the data. If it is simple HTML and a modern PC, showing it would typically be faster than writing it to disk; OTOH if it is a complex Excel file with lots of start-up macro's clearly writing to file would be faster since it does not require launching the app nor interpreting/executing the data.

Ok I get what your saying. But I did an experement with eathereal and saw that if you copy the file from a file server there is more chater on the network than if you open the file. I'm just wondering if the same applies to a download or open over the net.

Hello,
I managed to read a text file and read the text line by line by doing this:
using (StreamReader sr = File.OpenText(fullName))<br />
{<br />
string s = "";<br />
while ((s = sr.ReadLine()) != null)<br />
{<br />
Matrice de données<br />
}<br />
}<br />
the text is a matrix separated by a semicolon, such :
NOM;PRENOM;ADRESSE;TELEPHONE
FONEY;julien;14 rue grifuelhes;0123679470
.
.
How can separate each field?, With the result matrix can be accessed later, thank you very much.

ArrayList listOfLines = new ArrayList();
in loop...
string[] values = s.split(';');
listOfLines.Add(values);
then you will have a list of 'rows' where you can access the 'columns'
many ways to handle this, hope this gives an idea
... your prob best stroing in a dataTable actually

We don't use ArrayList anymore.

I didnt what to type System.Collections.ObjectModel.Collection<string[]>... but guess i have now 
plus i did 'edit' to say a dataTable would be a good alternative

IMO List<string> will do. A simple generics give you a typed ArrayList,
no explicit casting required any more.

You can Split the strings on the semi-colons to get the individual values.
From there you could populate a DataTable or a two dimensional array, whatever you like.

Hi,
i added an eventhandler to the ItemSend event of the outlook outfolder. It fires regular but when i use following code
1 void Out_Items_ItemAdd(object Item) {
2 log4.Debug("new item in outfolder added");
3 Outlook.MailItem mail = Item as Outlook.MailItem;
4 if (mail == null) {
5 log4.Debug("not a mail item");
6 return;
7 }
8 try {
9 moveMailItem();
10 return;
11 }
12 mail.Send();
13 } catch (Exception ex) {
14 log4.Debug("error sending item", ex);
15 }
16 }
when i now send a new mail it works and it calls moveMailItem().
My problem is when i send an meetingRequestItem it logs that this is no mailitem and exits the eventhandler. But then the item never sends. Its hanging in the outfolder forever.
I tried to explicitely call send on that item but i found no way to call send to it.
I tried to add Item = null after line 5 and called the Garbage Collection. It thens sends all Appointments that where hanging before on 3 PCs but on one PC there where not all items send out that where no emails and they sent where still in outfolder.
Can someone please give me an hint how this could be fixed?
