I have a combo box in the first column of a Datagridview. The displaymember is the inventory item key. I set the selectedvalue to the item description.
I have an event for "OnEditControlShowing" of the grid that checks to see if I'm on the combobox column, and if so, checks the selectedvalue to make sure it's not null. If both these tests pass, it wires up an event to the selectedchange on the combobox. This event populates the 2nd column with the selectedvalue of the combobox.
Problem #1, I have to click on the combo twice to get it to drop down.
Problem #2, there is no problem on the first row, but when I click on the combo and get it to dropdown on rows after the first one, the description displays "System.Data.DataRowView". How can I trap for this value so it doesn't display?
Thanks,
PF

I have a factory class that returns typed objects using generics. When run directly from an app, the code executes as expected, but when activated through remoting, I always get a null reference exception. When debugging, I cannot step into any server method that takes generic parameters, while regular methods execute as expected. Is this a limitation of remoting? Below is a code sample:
public class ObjectFactory {
//Works as expected
public int AddTwo(int first, int second) {
return first + second;
}
//Fails when activated through remoting
public <T> CreateInstance(string[] parameters) {
/* Ugly Details */
}
public ObjectFactory() { }
}
Any ideas?

I'm actually using primitive types right now to try and get some of the details worked out.

|
|
|

Just for kicks, I tried some other objects that I know to be serializable with no luck. Does any one have any other ideas?

When I use the Visual Studio 2005 DataSource Wizard to connect to an Access database, it seems that it hard-codes the connection string for the database file, but I can't find where.
How can I allow the user to dynamically choose a different database file at runtime, but still use the data-bound Grid View control?
Thanks

Background:
I need to read in 3 text files. Each file has it's own format. I decided to code a class for each type. Each class impliments some common methods:
getItem()
getDescription(item)
getCount()
In addition each class contains some items that are more specific to the data in that file. I originally had specified the name of the file to be read in the constructor. The constructor would then load the file (and it's associated data) into arrays then close the file. The instance would look like this...
fileReader1 fr1 = new fileReader1(sFileName);
It was then requested that I validate my input files. This is where my question lies..
What is the best approach for this functionality? Bear in mind I need to not process anything if the file is not valid. I am currently working on a 3 tier design (GUI, Logic, Data). The readers are called from the Logic layer. I have mulled the following:
#1 Move the ability to read the file from the constructor to a public method. Code a new method called 'validated()' that would return TRUE if the file was valid and then call the read method (this would be done from the Logic layer) if validated returns TRUE
#2 Continute to read in the file via the constructor, but only read the file if it is valid (via private validate method). If the file is not valid fire a 'not valid event' and catch it in my GUI.
#3 Create a seperate class called 'Validator' that I pass in the file to validate and the type. If this returns TRUE then continue, otherwise dont'
#4 Let the constructor validate the file. Set a bool variable in my reader class and expose it as a public property. If file is valid set variable to TRUE and call public read method.
I am interested in the best way, the 'professional' way to impliment this. Thanks in advance for your thoughts/comments.

Imagine the following was the commandline argument.
Path=d:\f\Backup\"Wolf's Documents"\"Visual Studio 2005"\Projects\HelloWorld\HelloWorld\bin\Debug\HelloWorld.dll
I already took care of the spaces in their with the quotes, but i tried everything i could think of to deal with the apostrophes in "Wolf's Documents" including one sites suggestion of using a '\' infront of them which didn't seem to have an affect.

1. Is there any reason this can't be Path="d:\f\Backup\Wolf's Documents\Visual Studio 2005\Projects\HelloWorld\HelloWorld\bin\Debug\HelloWorld.dll" so that one set of quotation marks takes care of the whole situation?
2. So, what's the problem?

I want to retrieve the icon used to represent a removable or local hard disk.
I know I can use SHGetFileInfo to get the icon if the disk exists, but what if the disk doesn't?
Basically I want to create a tree structure representing a device that has a removable disk and a local disk. These devices will exist on a virtual device that I am representing.
Is there a way to retrieve an icon for a Device that doesn't exist? i.e. can I specify something that denotes to SHGetFileInfo that I want a device's icon for a device's type that I specify?

Hi,
I'm calling a web service from my app and its execution lasts a few minutes, normally. I would like to leave it executing without making my app wait until it finishes. How can I do this? Some type of thread or something?
Thanx for any help!

using System.Threading;
...
public void myProc( object stateobject )
{
MessageBox.Show( "This is a thread." );
}
private void button1_Click(object sender, System.EventArgs e)
{
ThreadPool.QueueUserWorkItem( new WaitCallback( myProc ) );
}

Hey.
Can anyone help me with this.
I have an object, that can grow bigger or smaller.
I need to save it in a file after I encrypt it.
The problem -> How can I clear the file before saving new stuff in it? if I won't clear it, it will write in the start 1 object, then I will have the same object PLUS the new object, then I will have the 2 last object PLUS the new one.... etc...
So... How can I do it?
Thanks...
NaNg.

Well the FileStream constructor goes like this:
FileStream( string path,FileMode mode );
Now, FileMode is an enum with member names:
Append, Create, CreateNew, Open, OpenOrCreate and Truncate.
If you use FileMode.Create it will overwrite the old file or create a new one if the file doesn't exist.
Hope this helps.

Hi!
I'vw been having some odd problems with connecting elements in Dundas diagram. I have an Element with 3 ConnectionPoints ( on is an input, and two ara outputs ) and when I try to connect a second Element's input to one of the outputs it always connects to the same ConnectionPoint no mater which I specify in the code. Like:
ElementFunctionality.ConnectElements( myConnector , TheOtherPoint , myElement.ConnectionPoints[ "Yes" ] );
//and
ElementFunctionality.ConnectElements( myConnector , TheOtherPoint , myElement.ConnectionPoints[ "No" ] );
will both connect to the "Yes" ConnectionPoint of the elment. I've even tried connecting manualy without using the ConnectElements function. I'm realy out of ideas.
Can someone help? Oh, and here is a screenshot.
