1 - don't post so much code
2 - tell us what line your code crashes on
3 - use the debugger to see what object is causing the crash, and give us more info that way, too

the line causing the problem is this:
sql_command.Parameters.Add("@vehicle_make", SqlDbType.Int).Value = Convert.ToInt32(cboVehicleMake.SelectedValue);
i guess because during the combobox creation it's still filling the values so it will find null value in the vehicle make but i don't know why thought i am populating the vehicle makes first?!

i am developing a desktop windows for application but i don't want to include the sql management express with the application therefore i want some way to do my sql statement (in case of troubleshooting) and i want to that from the same application (via admin user)
so if i place a textbox to enter the sql statements how can i view the output?
|

|

what about multip statments like in sql management express i can do this:
select * from company;
select * from employee?
how about errors output?

A TabControl with a TabPage for each result set.
When I get messages I put them in a DataTable and treat them the same.

I second using datagridview as suggested.

I have dragged a toolbar off the toolbox onto my winform. I then opened the Buttons collection and added a button.
I can't for the life of me figure out how to set the button's image.

Are you doing this at runtime or in the designer?
What about the DisplayStyle and Image properties
(assuming ToolStripButton class)?

Hello,
I would like to write a function in VS2008 C# that I can use in Excel2008.
I tried with this template that is available in VS2008 TeamSystem called "Excel 2007 Add-in" - when I write some code in this provided "ThisAddIn_Startup" function it works - but I would need to write my own function (e.g. something like: public int AddMe( int a, int b ) { return a+b; } ) which is accessible from within an excel cell like =AddMe(3,4).
Any help would be highly appreciated
regards, Dussel

I have a class that has a property that is a struct of two Int64s. Similar to the Size property which is two Int32s if that explains it better!
How can I get this to be usable in the property grid?
At the moment, as a workaround, I've made this property private and created another public property of type string and used the struct's ToString and TryParse methods in the getter and setter to alter the original property.

I figured it out 
For anyone that comes across this I needed to:
1. Create a convertor class that derived from ExpandableObjectConverter
2. Override CanConvertTo
3. Override CanConvertFrom
4. Override ConvertTo
5. Override ConvertFrom
6. Apply the TypeConverterAttribute to the property

Hi,
Can We Use Windows Presentation Foundation in .Net framework 2.0?
|
|

|

No. It started in .NET 3.0. Are you trying to use something you created in WPF with something else done in .NET 2.0? That may be possible, but the WPF isn't in 2.0....

No but if the reason you're asking is because you're using vs2005 then you can add the extensions. Just google for vs2005 wpf

Hi all im trying to convert a .dll call method from VBA to C#
VBA Code look like this:
Public Sub SnodAnrop()
Dim result As String
host = "***"
port = "***"
user = "****"
pass = "**"
cert = ""
cacert = ""
service = "**"
arg = vTyp & pnr & datumIn & datumUt
extra = ""
result = Space(1024)
buf = 1024
i = Module1.snod25x(host, port, user, pass, cert, cacert, service, arg, extra, result, buf)
SnodError (result)
If sFel = 0 Then
result = GVRSvar(result)
WriteToFile (result)
End If
Declare Function snod25x Lib "sn25.dll" Alias "****" (ByVal host As String, _
ByVal port As String, _
ByVal user As String, _
ByVal passwd As String, _
ByVal cert As String, _
ByVal CAert As String, _
ByVal Nodtjanst As String, _
ByVal arg As String, _
ByVal extra As String, _
ByVal result As String, _
ByVal Resultbuf As Long) As Long
And i have come this far in C#:
private string result;
[DllImport("sn25.dll", EntryPoint = "****")]
static extern int snod(string host, string port, string user, string passwd, string cert, string CAert, string Nodtjänst, string arg, string extra, string result, int buf);
private void button1_Click(object sender, EventArgs e)
{
result = new String(' ', 1024);
string user = "*****";
string pass = "***";
string service = "GVRPOSDIAP2";
int i = snod("*****", "****", user, pass, "", "", service, textBox1.Text ,"", result, 1024);
textBox2.Text = i.ToString();
textBox3.Text = result;
}
This two code strips are the same. In different language.
The Problem is that dont get any result back, its empty, but in the identical code in VBA its returning info at string result. My Question is how can i write the code in C# so a get back info at the string result????
The int i is giving me status back witch is 0 that meens OK but no info in return!!
Please Help Me!!
Thanks

My Fellow Coders,
Good day.
I need to write a .dll that will read and write to Excel and Access. Is there an existing code that I can use? Is there an example of how to do this that is endorsed by microsoft and the .net 3.0/3.5 framework.
I tried an ADO.Net approach but ran into errors and read on msdn that approach is not encouraged.
Any help you can provide would be great.
Thanks in advance.

A .NET assembly? If yes you need to look into the Primary Interop Assembly[^] for each product.

Like led mike suggested, look into the Interop Library. I use it on a regular basis for client reporting tools and it is good to have around.

Gentlemen,
Thanks. Does the Primary Interop Assembly come with Visual Studio 2008 Professional?
Thanks again,

Ok, uh try this, click on the link I gave in my post, then (and yes, I know this is very unpopular with programmers these days) READ THE ARTICLE.

Hey, have some mercy, I'm new at programming 
Thanks for the information. I think that will be what I need.

Sure. Like Paul said I think you will find it very easy to work with. Of course the complexity of the Object Models are still there but they provide all the conversions into .NET types for you so it's pretty sweet.
