it doesn't work because listbox doesn't implement the ISerializable interface...
try to serialize the datasource of your listbox... if it is an array of string,
it can be serialized without any problem.
|
|
|
|
|
I'm sorry for the complete ignorance, but how do I serialize the datasource?
do you mean serializing each string, one by one?
|
|
|
|
|
try this:
<br />
string[] items;<br />
items=new string[listbox.Items.Count]<br />
for(int i=0;i<listbox.Items.Count;i++)<br />
{<br />
items[i]=(string)listbox.Items[i];<br />
}<br />
info.AddValue("List",items);<br />
|
|
|
|
|
still not working... 
I get a null exception in this line: ('cnt' in my program is the 'i' in your example)
items[cnt] = (string)lbText.Items[cnt];
I get the exception in cnt=0 even though lbText.Items[0] has a string in it, and it is not null.
|
|
|
|
|
okay, I figured it out, and it serializes the array, but it serializes only the first item.
|
|
|
|
|
hmmm?!
it should work! perhaps you don't serialize/deserialize with the right type?
try this:
serialize:
<br />
string[] items;<br />
...<br />
info.AddValue("listbox",items,typeof(string[]));<br />
deserialize:
<br />
string[] items;<br />
items=(string[])info.GetValue("listbox",typeof(string[]));<br />
|
|
|
|
|
it works! 
I had to turn the items[] into a member because thats what I need to serialize in the serialization command:
BF.Serialize(stream, items);
and if I just create the array in the serialize or the deserialize it doesn't exist for me to serialize.
Thanks alot!!!
I have just two more REALLY small questions (and I think your the MAN with the answers!):
1. is there anyway to serialize an object as is? I mean, list
just serializing a listbox or a combobox, and all the infomation inside will be saved?
2. I don't get exactly what the Initialize() command in the array class is doing, or when should I use it...
Thanks Again!

Search for "Control.DataBindings Property" in your vs.net help or msdn.
I think that's what you are looking for.

Mostly you don't need to call this method. For example you have an array of string, the compiler sets all strings inside this array automatically to an empty string.....

How do I add a line in a textbox through code to display something like this?
111
222
333
Rather than.
111222333
Thanks, this is easy, but I forgot what the sort code was, I think that it was like &ensp or something. Thanks.

\r\n should do it.
111\r\n222\r\n333

As the two posters above me replied, you can use "\r\n" or Environment.NewLine. The latter option is the recommended one though. It'll work depending on the platform you're running on, for eg. Unix's newline character is only "\n".

After creating an application in C# that runs fine on my computer and another developer's computer, we included it in an InstallShield project. When we try to run it we see the message box saying:
Common Languge Runtime Debugging Services
Application has generated an exception that could not be handled.
Process id=0xb3c(2876), Thread=0xb40(2880)
Click OK to terminate the application.
Click CANCEL to debug the application.
I've created a Release version but that didn't seem to matter. We have another program that's written in .NET that works fine. I've seen many postings on this error on the net but no solutions. Any ideas?

The most common thik of an error msg like this listed below (as I know):
- framework not installed
- some require component not installed/registered
So if you use a dll or ocx you must register it, in the other machine too.
eg.:
from command line:
regsvr32 mycomponent.ocx
or
regsvr32 mycomponent.dll

Actually you are close, we figured it out. My program is using an Access database via a datasource connection. When the program begins to load, it attempts to connect to the datasource. Unfortunately the connection path is hardcoded and the installation computer did not have the same directory structure. So when the program started it could not find it's datasource. We changed the path and moved the database to the right directory and it worked.
Ahhhh engineering!
Normality is a weakness...

Use a RichTextBox.

Owner draw. Which also applies to a TextBox, if you don't want to go the RTF route.

You might check out the documentation on the RichTextBox here[^].

Hi im programming with the enterprise library, where can i find help for it? some guides for programming dataconections, dataaccess...thanks
|

There's about 10 MB of documentation and quick starts that come with the distribution. Look for the "Docs" and "QuickStarts" directories sitting under where you installed it.
You can find info on the official site[^, as well as a group of webcasts[^] that are pretty informative, if you don't mind the rather jovial tone of most of the sessions.
There are also links to more information on Channel9[^].
There is no shortage of information about the Enterprise Library. All you have to do is look for it. Google is your friend.
