After a bit of Googling, this article seems to mention something that sounds like what you want.
Here.[^]
Scroll down to "Using Attributes in PropertyGrid". I have never really used a PropertyGrid before so can't really help you much more than that.

You can mark properties as readonly using the ReadOnlyAttribute.

Hello,
if a commercial product is an option for you, only Smart PropertyGrid will give you the flexibility of choosing a disabled mode for the PropertyGrid. By descending order of "disabled" importance:
1. It can be completely disabled (nothing is actionable, not even the scrollbar).
2. It can be completely disabled (nothing is actionable except the +/- signs and it is scrollable).
3. It can be disabled with the properties still selectable and scrollable.
4. It can minimally be disabled with the property values selectable so that you can copy their value.
The PropertyGrid doesn't handle a direct way to disable everything. You would have to set a hardcoded Readonly attribute on your properties or to publish dynamically a Readonly attribute for your properties with a TypeConverter or Type Descriptor... not very easy for a simple requirement...

hello,
I am having a listView control with two columns. I want to insert some data first in column 0 and then in coulmn 1. The each column data is not related to other column(means not a subitem of any item).
How can i fill all related data to column 0 in first loop and then in Column 1 of a ListView control?
Also, I want to provide only column separator line in ListView, How to do it?
Thanks.

You can refer to columns of a listView just like an array:
myListView.Columns[0].Text = "This is the first Column";
Would set the column's header to the above text.
For further info about ListView's other properties, see this article.[^]

Hello Friends,
I want to save text in a image format it may be JPG or BMP
I have three labels at form now what i want that whatever written of these three labels will save in a single image.
like
''''''''''''''''''''''''''''''''''
Hello-------Label1
Dikshant----Label2
Hi----------Label3
''''''''''''''''''''''''''''''''''
These three labels are in this form so please tell me how can i save these three labels data in a single image...
|
|
|
|
|
Use the DrawToBitmap method of the form to draw the form on a Bitmap object. You can then use the Save method of the Bitmap object to save it in the file format you like.
If you want less than the entire form, put the controls in a Panel, and use the DrawToBitmap method of the Panel.
Despite everything, the person most likely to be fooling you next is yourself.

Hello sir,
Thanks for Answering my Question....
As i am new in C#.NET can you please send me a sample code so i can easily understood..
Thanks in Advance
|
|

The code is basically:
using (Bitmap b = new Bitmap(form1.Width, form1.Height)) {
DrawToBitmap(b, new Rectangle(0, 0, form1.Width, form1.Height));
b.Save(fileName, ImageFormat.Png);
}
You can check the parameters to use in the documentation:
MSDN Library[^]
Tip: search for drawtobitmap method or bitmap class.
Despite everything, the person most likely to be fooling you next is yourself.

|
|
|
Create an instance of the bitmap class, and draw on it the text and then use Bitmap.Save

The error code under BitsDownloadErrorException code is 0x80190194 in hex. Windows error codes are defined in WinError.h (which you can find under vc\PlatformSDK\include under Visual Studio's install folder, if you installed the C++ tools). Error codes are grouped into 'facilities' to allow codes to be allocated independently. The 'facility' part is the second byte of four, here it's 0x19 = 25 decimal. Facility number 25, according to WinError.h is FACILITY_HTTP, so it's an error defined by the WinHttp APIs.
I can't find where this is actually used, but the last 16 bits are always the specific error. 0x194 hex = 404 decimal, which is of course the 'not found' HTTP status code.
Assuming that you've copied the files to the right location, I'd check that your web server is configured to send that type of file. IIS 6.0 only sends files that it knows the MIME type for, in contrast to earlier versions. The Updater Application Block 2.0 FAQ mentions this and how to fix the issue at http://msdn2.microsoft.com/en-us/library/ms978569.aspx#updaterfaq_deploytopic5[^].

Hi,
I want to make some simple OCR actions using C#.
All I want is a DLL. I'll give him an image, it will return a string.
Can you give me such dll please?
Thanks

OCR is not trivial. Atalasoft have a commercial library, I don't know of any others.

I know it's not trivial but in my case I need a simple OCR functionality - only recognize numbers.
I forgot to say - I want free DLL, not commercial.
Thanks

I guessed that. You're not very likely to find one, sorry.

Am developing An application in C# and picking data from the database.
I have a bit data type to act as a flag.In the datagridview it displays a checkbox(good for me) but then I have failed to handle the click events of each row clicked to flag off the row so that it is not displayed again.
Need some help or a good article handling this.

Following is my issue.
-------------------------------------------
I have a unmanaged application ( C++ , .exe ) which has a class CMyClass
with a public member fMyFunct(). You can assume this C++ application is built with /clr option.
I need to instantiate CMyClass in a different managed ( C# ) application and call fMyFunct().
Many thanks if any of you can send me a sample which demonstrate above things ( Remember I can't manipulate C++ application apart from project settings. But you can do anything in C# application )
----------------------------------------------------

If it's an application ( not a dll ) then if you can't change the app, you're basically screwed. Your best bet would be to abstract the class/method out into a dll, so your C# application can construct an instance and call it. I don't think you can add a reference to an exe in a .NET app.

Sorry, you posted way too much code for anyone to bother reading it all.
Did you try setting a break point here and on any other code that sets that width of your control ? Does the control have a minimum or maximum width set in it's properties ?
