I am using Crystal Reports.Net 2002. How do I connect to a password protected Access database? I have gone through the Report expert and chosen the database and entered the password.
When I run the program however a "Database Login Screen" comes up asking for a: ServerName, Database, Login ID, and a Password. I tried to enter the Database path, I used "Admin" for the Login ID and the Password but all I got was "Login Failed please try again". I tried just entering the Database path and Password but got the same "Login Failed please try again" screen.

Do you found any solution to implement this with .net?
Are there any libraries available?

Press any key to continue
any idea why it so !!
earlier i deleted the table manually from the Enterprise Manager is that the cause for it

By Manually deleting the table you did remove it, but there may still be a pointer to the table. In other words the application still thinks the table exists, but cant find it? Try 'Manually' recreating the table (only with minimum data, no need to create entire thing). Then using the proper commands empty the table, THEN delete it. that may fix the problem. otherwise you may need to use a maintenance routine to rebuild your database.

Hi,
I currently have a datagrid that is displaying items in an inventory. The user is able to modify inventory contents, and then there is a button to save the changes back to the SQL database.
What I would like to implement is something that will change the color of each row that the user has updated.
The only thing close that I've found is DataGrid.SelectionBackColor but the problem with that is that it changes the row color of the currently selected row, instead of row[x] in the DataGrid. So if the user moves the mouse to select a different row, the updated row loses the color, and the newly selected (non-updated) row gains it.
Anyone have a solution for a DataGrid to change the color of any row and then have it remain there?
I noticed you can't even get to an individual row with the DataGrid, there is no DataGrid.Row[x] feature. If there was, it might have a nice DataGrid.Row[x].BackColor property I could use.
Thanks in advance,
Steve

You can use obj.GetType() to find out what type object actually is. You can then cast it to the proper type.
Or you can do something like:
if(obj is int)
int x = (int)obj;
else if(obj is string)
string x = (string)obj;
else ..

Here is the situation.
I have a Form, called Form1 that contains a button, this button is marked as private.
I have another Form, called Form2 the inherits from Form1.
I Want Form2 to be able to Show and hide the button in the base class, without exposing the button as protected / or public.
I Have created a public property on Form1 which has Get/Set into button.Visible property. All should work ok i can hear you shouting.
In the form2 designer, i can see the property mentioned above, and i can change its value, and the button obediantly shows and hides it self as expected. The problem is that When i set enabled to true, it adds code to the designer generated section, which speifically sets my property to true, and when i set it to false, it removes this code, but it does Not add code to set it to false. The defualt value of the property is set to true, but this has no effect.
I realise i can call this property in my form load, or in a constructor, but i would like to get the design time support. Other properties such as Enable work fine.
Any idas?

Try to add DesignerSerializationVisibility attribute:
<br />
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]<br />
public bool Description<br />
{<br />
get<br />
{<br />
return myButton.Visible;<br />
}<br />
set<br />
{<br />
myButton.Visible = value;<br />
}<br />
}<br />

Unfortunately this does not have any effect. I believe that for some reason the designer believes the default value is set to false, so that when i set it to false, it does not add any code.

In framework 1.1 I used to do Assembly.GetTypes() and get everything, web pages, web services, classes.
In framework 2.0 it’s not the same story. There are App_code…dll, App_Global.dll, App_web…dll.
The only thing I was able to get is the App_Code by ReflectionOnlyLoadFrom() method.
Is there a way to get everything like I did before?

Code :
internal void Run()
{
AppDomain curDomain = AppDomain.CurrentDomain;
curDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(MyReflectionOnlyResolveEventHandler);
string assemblyPath = Path.GetFullPath(assembly.Location);
m_rootAssembly = assemblyPath;
Assembly asm = Assembly.ReflectionOnlyLoadFrom(assemblyPath);
// force loading all the dependencies
Type[] types = asm.GetTypes();
// show reflection only assemblies in current appdomain
Console.WriteLine("---- Inspection Context ----");
foreach (Assembly a in curDomain.ReflectionOnlyGetAssemblies())
{
Console.WriteLine("Assembly Location: {0}", a.Location);
Console.WriteLine("Assembly Name: {0}", a.FullName);
Console.WriteLine();
}
}
private Assembly MyReflectionOnlyResolveEventHandler(object sender, ResolveEventArgs args)
{
AssemblyName name = new AssemblyName(args.Name);
String asmToCheck = Path.GetDirectoryName(m_rootAssembly) + "\\" + name.Name + ".dll";
if (File.Exists(asmToCheck))
{
return Assembly.ReflectionOnlyLoadFrom(asmToCheck);
}
return Assembly.ReflectionOnlyLoad(args.Name);
}

I am writing a .net assembly that contains several UserControls. When a control is clicked, I would like to fire a message to the parent window so it can do something.
The parent window is in a different assembly, and the UserControl knows nothing about the parent.
How can I call the parent?
In MFC/Win32 I could send a message, but I'm new to this C#.NET thing. Is there a standard method to do this?

i think u can use the on click event of the control
and use the SendMessage(hwnd,wparam,lparam,..) to send
a message to the parent window
Regards,
Pramod

The UserControl needs to raise an event. Any host (parent) can choose to respond to the event if it wants to. This is the .NET way of doing things and it's much better than the old SendMessage way.
Look up events and delegates in the documentation.

There is no "simple" way to do this. You can find an example of RAW printing here[^] on MSDN. The code is in VB.NET, but is easily convertable to C#.

OK. You can do it the hard way then -> this[^] is how to do it.
