May following code snip helps you

Graphics g1 = button1.CreateGraphics();

            for (int i = 1; i < 100; i++)
            {
                SizeF size1 = g1.MeasureString(button1.Text, new Font("Verdana", i, FontStyle.Regular));
                if (size1.Width > button1.Width)
                {
                    button1.Font = new Font("Verdana", i - 1, FontStyle.Regular);
                    break;
                }
            }

Not working. Sorry I did not mention the Button is docked to Full; button1.Dock = DockStyle.Fill;

I am always getting the button1's width as 2.

C# + COM Advanced Question

Hi Coders,

I have a C# application that lists the functions in a COM object via reflection. My COM object has very useful descriptions for each function defined in it's IDL using the 'helpstring' attribute, such as:

[id(24), helpstring("Here is the function description.")]

I am desperately trying to find a way of getting this text in the C# application via reflection. Is this possible? Is there a Platform API function I can PInvoke to get a COM function's description?

Have been investigating for a while but to no avail, any help would be much appreciated!

Thanks in advance,

Dave

You can use the ITypeLib (or ITypeInfo) interface to retrieve this information via the GetDocumentation[^] method.

you can hide your controls according to your requirement or dynamically add controls according to the requirement. But first one will be easy while compare to the second one.

Entity Framework Lock up issue please help, wierd problem !!

Hi all, i am experiencing a program lock up issue using entity framework and object datasource..Let me explain the problem..

As usual, from the datasources i choose my entity object and drag some fields to the windows which are a mixture of combobox, some fields are empty and some fields are are filled before. The problem is, when i enter a text to a textbox or choose a value from a combobox, the program just wont let me choose another entity object field on windows or close the program, even BindingNavigator wont work..The only way to proceed and get the program out of stall is to change the row `from` the datagrid..Normally i would want edit all the fields i have on the windows and proceed to the next Record, but the program just stalls at the entity object field i edit on the windows..

Help would be very appreciated, its urgent

Bundle SQLEXPRESS with application

Hi Guys,
I've just finished an application that uses MSSQL EXPRESS as its local temp DB. I just wanna ask, for convenience sake, is there a way i can put SQLEXPRESS into the installation such that it installs "silently", with the other app. I mean, without the user having to run the .exe by himself.

He who goes for revenge must first dig two graves.

You can make your setup program download and install it as a requirement. It would download it from the MS site. No need to actually bundle it.

Maintain a custom collection and add the newly searched item in the list every time. Bind the data grid with the collection.

Though your message subject a bit different than what you want to achive ( you are actually not searching grid rather trying to display appened result Laugh | :laugh:

it seems ), here is how you can achive that

1. Create an empty DataTable with columns that you want to display in grid.
2. Get the seach result from DB and "append" new result set ( one or more row which comes as your search result)
3. Bind the "updated" DataTable object to grid.

Let me know if you can do that.
Let me know if I have misunderstood your mesasge.

Thanks,

Method overloading

i gr821-Mar-10 19:48

i gr8

21-Mar-10 19:48

How to access particular method in overloading

E.g: 2 overloaded method as follows

Method1(double, double)
Method1(int, int)

calling method:

Method1(1,1)

Here from calling function i want to access Method1 with "double".

how can we achieve this.

Cast the variables to the expected type, as follows:

Method1((double)1, (double)1);

Re: Method overloading

This will by default call Method1(int, int).
