You're getting the Application Error on sqlConn.Open, and only on that specific machine? How does the connection-string look when you debug the application?I are Troll

Answer to Q#1.1: Yes the application error is on sqlConn.Open.
Answer to Q#1.2: Yes, this is reproducible only on some machines.
Answer to Q#2: connection string looks like this - "Data Source=computer-88\\sqlexpress;Integrated Security=SSPI"

Looks good, doesn't seem to be a problem with the code. It was on a specific machine? Could there be another application running that's using the same port as SQL Express?
You might want to try to connect over IP, using the default port-settings. If it helps, we'll have a clue where to look next  I are Troll

Hi All,
I am inserting a toolStripSplitButton into the ToolStrip. And all the things are going fine.
At run time. when I select a Item from a DropDown items, the button part of the Split Button doesn't comes into the Pressed state.That is end user will not get to know that the item is selected.
I want the button part of the Split Button should work like a toggle button when a item is selected from DropDown or from the Button directly.
Let me known about the rendering if required, I do not know much about Rendering.
thanks
Rahul Kapoor.

Sir, let me know how can I set a read only property ?
Let me know something from the corner.
|
|
|

My bad, I mixed up the ToolStripSplitButton with a ToolStripButton. The property is indeed readonly, I didn't find any "nice" solution to display the button in a checked state.
It has been reported on Microsoft Connect[^] in 2005, but it doesn't mention what version of the Framework that this applies to.
There's no Checked property in the ToolStripSplitButton, nor in the ToolStripDropDownButton. That leaves only the option of extending the controls and building the desired functionality yourself, using owner-drawing.
I found a thread of someone who did that here[^].

1) analyse your requirements & document them
2) do some research and see whats out there that may assist
3) do a design, include logging, monitoring, test plans etc
(you may need to iterate through 2 & 3)
4) write some code to implement the design/missing pieces
5) test
6) when you have specific coding issues, post code, symptoms/diags etc back here
easy !

As Garth said; furthermore try using normal language, not txtspk, and when you later need to show some code please use PRE tags to achieve best readability.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. [The QA section does it automatically now, I hope we soon get it on regular forums as well]

You use the *.dll and all you have to do is:
MyGenericDataGridView gexp =
new MyGenericDataGricView("XLS",datagridview1, MyExcelExport.Theme.BlueSky,null,null);

Hi there,
I was wondering if it is possible to take a windows application and load the contents of the main window inside my c# application as either an MDI window or in a child control of some sort. At work we use some old software where each "module" is a seperate exe with its own window and I wanted to build a c# app with tabs or MDI windows or something to make it a bit more usable. We do not have access to the source code and its not managed code for sure. At first glance, it looks impossible, but I was hoping there was some sort of p/invoke or activeX magic out there. Thank you code project!

You can make it "look" as if an exe is running from your application using the SetParent API. To find out how, visit this CodeProject article

Thanks, that code did exactly what I needed it to. With a little customization, I got it so anytime an exe from our old software tries to run, it gets loaded in a tab on my program instead. Very cool!
Thank you so much!

Possible? Sure, but wise? That's another question... You are going to end up with a mish-mash of menu and tool bars (each app will have their own in their own window) and it is not going function like your typical MDI interface at all really.

private struct modelStruct
{
public string theModel;
public int theModelID;
}
private modelStruct thisModelStruct;
private ArrayList availableModels = new ArrayList();
I add some items to the arraylist. Then I want
cboModel.DataSource = availableModels;
cboModel.DisplayMember = "ModelID";
cboModel.ValueMember = "theModelID";
But I need to do some casting or content exctraction, but where and how? For DisplayMember the combobox shows "ToolHistory.History+modelStruct".
I have tried cboModel.DisplayMember = thisModelStruct.theModel; but it makes no difference.

AFAIK your data provider must have properties, not fields, of the specified name(s) for data binding to work.

Greetings
I want to build a windows application that can connect to a webserver for user authentication.
for eg
when we install an IM messenger it's jus like a windows form application. But to authenticate a user it connects to a server.
How can I achieve this functionality.
Plz help.
|

|
- Build a service that offers an authentication API, typically by verifying a user's credentials stored in a database.
- Build a client API that communicates with this service.
- Call the client API from your Windows application.
I recommend using WCF to simplify this task. You can host the service in a Windows service, a standalone app (uncommon, but useful for testing) or a web app.
