I found my own answer...
I have to use the ColumnChanging event on the table and use the following code:
void ColumnChanging(object sender, DataColumnChangeEventArgs e)
{
if (e.Column.DataType == typeof(string))
{
if (e.ProposedValue.ToString().Length > e.Column.MaxLength)
e.ProposedValue = e.ProposedValue.ToString().Substring(0, e.Column.MaxLength - 1);
}
}
Life is not short... the problem is only how you organize yourself

Hi,
A treeview control is populated with data
i.e.:
item1
subitem1
subitem2
...
Not sure why when I click on a subitem, the image changes. There are no events that fire this.
When assigning the images, I do assign using imageindex and selectedimageindex
Note that clicking on the parent i.e. the item does NOt change the image whereas clicking on the subitem does.
Do you know why this is occuring please?
Thanks

Hi,
There are duplicate properties for unselected and selected items, e.g.
TreeView.ImageIndex and SelectedImageIndex.
Check the documentation.

Hi,
Do not understand what you mean.
Coul dyou please explain?
p.s. I am still searching the msdn for this.
Thanks

Hi,
PLease note that the image index for both selectedimageindex and imageindex are set to be the same
So the question is why the image changes when i click on a subitem.
Thanks

from what to what? from one of your images to another one of your images?
If anything is wrong, I expect it to be either a bug in your code which we haven't seen,
or a Windows bug which I personally haven't heard of.

Yes, it changes to an image with the index 0
When I click away then the original comes back on.
There must be a bug in my code and that is why I am trying to solve this.
Thanks for your time.

Open up note pad, hold the left control and press backspace. You will produce a rectangle box character which i am not sure if it has any function or not in the operating system but when i pull data from my database, these characters appear where i believe are to be carriage returns.
is there a way to parse/seperate those garbage characters out while still leaving them in the database? If the data is bound to a richtextbox control, the text appears formated with carriage returns correctly
im stuck...

is it possible that the data is Unicode and you're treating it as normal ascii, or vise versa? i've accidently set varchar columns in the db to use nvarchar and it did some wierd things until i changed it back. they could also be special formatting characters that work in rich text, but a singleline textbox cant show them.

you could use regular expressions to filter the output for testing(until you figure out whats wrong) and only allow certain characters or classes of characters and see what fixes your problem, it isnt a very good permanent solution but it should let you quickly see what is causing the problem and figure out a way to prevent it from bieng loaded into the db or find a way to quickly get rid of it.

Hello...
I have a collection, derive from CollectionBase.
If I put that collection to PropertyGrid, I cannot see the item in list.
It shows only Capacity and Count.
How to do that ?
Thx...

Hi,
I'm trying to find out if this is possible, and if so how to do it. From a machine running XP or Vista, as I understand it, when you send something to print, Windows/the print drivers render the file into a format the printer can read and understand (a spool file?). This file is sent to the printer then the local copy is deleted. I believe this file is held briefly in the 'C:\WINDOWS\system32\spool\PRINTERS' folder, which is effectively the shared print queue folder. for all printers on that machine.
My question is whether you can capture this 'raw' spooler data (I've managed to copy and paste to capture the files that appear in the spool folder, but you have to be fast!), and crucially, once you've captured it, can you then somehow send it to print again?
I have a feeling this is more complicated than I think. Presumably there are different formats of spooler data etc? Is there a utility that can do the printing/viewing of captured files?
|

You could write something to monitor that directory and capture files that were created. I'm not sure if your copy of those files would cause problems in the printing process if the file is in use (the program copying it) when it is attempting to be deleted.
There are ways to send the raw files right back to the printer to print again. But you need to realize that each printer has its own language. The Windows printer drivers take the documents and convert them to the language of the printer. So I'm not sure you could create something generic for all printers...

say i was only given port numbers of all running servers in a particular LAN network.
Any hint on how to obtained the corresponding ip addresses for these ports?
Thanks in advance
|
|
|
|

Get the Ipaddreses of your lan first u can use command "net view" it gives the machine names of all your network , then get the corresponding ipaddress of each machine, then combine ipaddress combination with your port list and ping, if u got answer then u have the correct ipaddress.

i think you misunderstand how IP addresses and ports work
think of a street with 10 buildings, each building has 10 flats and each flat has its own mail box. Now in this example the IP would be the buildings physical address and the port number would be the flat number.
an IP points to a physical machine on a network and a port points to a specific service on that machine.

ok then use telnet<ipaddress port=""> if it gives the answer then u have the ip.
|

No you don't. All you have is the IP of a server with that port open. You may have multiple severs with the same port open. All of your servers may have that port open. You don't know you've got the one you were looking for.
There is no way to resolve a port address to an IP address.

you say server but you mean client i supose, right?!
If you are the client you have to know the server ip in order to connect to network (how would you locate him otherwise?), but you don´t know the ip addresses of others clients like you.
If you are the server you know the ip from all your clients ok?!
because if you let then in your network you get their id (meaning ip address).
Why don´t you download some server/client application here in codeproject to take a look at the code?!

Reply on the trhread you started - not on a new one 
I've just noticed, the dateTimePicker already has a check box which handles this automatically which can be made visible by setting the ShowCheckBox property.
