Hey,
I'm using a property grid control to display some user options for my applications. So, basically I have a big Settings class with all the properties associated with the property grid control and then the user can just change them.
However there's a help frame in the property grid control and I'd like to be able to display some help text in there for each property : pretty much as Visual Studio does.
Can someone help please?
Thanks
Allad
PS : if you know of an easy and prettier class for options dialogs in C#, I'm all ears.

You can use the DescriptionAttribute[^] class to set the text of the "help frame" of a property grid. In addition, you can use the CategoryAttribute[^] class to group related properties within the grid.

thanks a lot. It's working perfectly. Is it some kind of hack? It doesn't look like usual C# syntax.
Anyway, It is exactly what I'm looking for.

Nope, no hacks required. It was designed to look that way.  It's C# attribute[^] syntax. .NET allows you to attach additional bits of "metadata" to .NET objects (assemblies, classes, methods, and properties). Other .NET objects (such as the PropertyGrid) can then extract that data for their own purposes (such as displaying descriptions of properties).

Wow. Thumbs Up man. you got to be some kind of C# guru to know all that stuff.
Thanks a lot for your time. Now I may sleep with a better conscience.(I don't really like using hack stuff when I can help it).

Allad

Hello All

Currently, we need a pdf library which it could open a pdf file and get the pdf version information. if the library include version conversion function will be a big help for us.
Thanks

Hi!
The PDF-Version is listed in the header of the PDF-File. You could just open a stream, read in the first couple of bytes and then compare the version signature with what you want to make sure and that's it.
Would be like 7 lines of code and not library needed.
Regards,
Stevie

Hello Stephan
Thanks you very much!
as you said, the first line of the pdf file kept the pdf version info.
%PDF-1.5, means the version of the pdf file is 1.5.
%PDF-1.4, means the version of the pdf file is 1.4.

Are you sure your service is being run from the bin\debug folder? Also, does your CamToJ2K.dll have any dependencies that might also need to be copied to that location?

Hi,
I made a .net assembly which in which I put an activeX control called DSOFramer. I have converted this in a windows control library and compiled it and installed it in GAC.
This library contains the code to display and edit the office documents similar to DSOFramer control. This same code when tried with DSO Framer and windows application it is displaying the documents. After this,
I tried to put this control on a web form, by using
/* <object id="DSO1" classid="
"DSOControl1.dll#DSOControl1.FramerControl""
width="800" height="300" style="font-size:12;">
<param name="FileUploadURL"
="" value="http://localhost/ServerFileUpload/UploadFile.aspx" />
<param name="MaxSessionUpload"
value="10646" />
*/ tag as above.
But here its not displaying any word or excel file. Could anybody please tell me whats wrong with this and how should I achieve my target. Please tell me if you know. Please.

Hello All,
I'm working on a project where I'll have multiple controls on a Windows form that may get updated when messages are received on a socket being listened on by a worker thread or the controls might get updated from the main thread.
The way I currently understand it is I need to set the controls properties using a delagate if control.InvokeRequired is true.
How could this be done without having to have a delagate method for each control on the form? There are many of them and they all could be updated from the worker thread.
All advice is appreciated.
Thanks.

Try reading up on the SynchronizationContext class. This article[^] might be a good start.

I am designing a control that will be manipulated BOTH at run time and design time through a property grid. I have some properties that I would like to hide form the run time property grid as they are not part of my run time interface so to speak (IE: Have no bearing on the run time user experience).
I see this happening already because at run time, when I attach the property grid I am not seeing any of the properties that are in the native 'Design' property category so I know it can be done.
I have tried the simple thing of just putting my properties that I want hidden in that same category but no dice.
I found an attribute called 'DesignOnly' that seemed promising but it does not do what it sounds like it does. MS docs say that it can be used to make a property read only at design or run time, not make it invisible. I found an article in Visual Studio Magazine that seems to indicate different however and have written the author asking him. His article says the following:
"The convenient design-time–only DisplayImageIndex property lets control users pick which image to show. You can apply two attributes to this method's declaration: <category ("design")=""> tells the Visual Studio Properties browser where to list the property, and <designonly(true)> hides it at run time."
Are there any takers out there?
Before you reply here, I already now that you can use the 'Browsable' attribute and hide the property, but this hides is from BOTH design time and run time property grids.

These properties probably have the EditorBrowsable attribute applied with the state set to EditorBrowsableState.Never. In addition, they may also have the Browsable attribute applied and set to false.
You can get more information on the EditorBrowsableattribute here:
http://msdn2.microsoft.com/en-us/library/system.componentmodel.editorbrowsableattribute.aspx[^]
You may want to use EditorBrowsable with the state set to EditorBrowsableState.Never, which states:
The property or method is a feature that only advanced users should see. An editor can either show or hide such properties.

Hi,
As part of an application I'm writing, I created a simple help form. basically, I'm just displaying an html file in a webBrowser component.
As of now, I'm loading the html file from my personal server but obviously that solution doesn't scale for a large number of users (at any rate, not with my home brewed linux-apache setup).
I know there is a way to load html files from the resources into the web Browser control but I have not idea how to proceed. I gave it a shot and included a help.htm as a file resource in my form and then called webBrowser.Navigate("res://help.htm") but it is not working.
Can anyone help please?
Thanks a lot.

I dont think you can do that in a simple way. Here are some ideas:
- distribute your help text as one or more separate files
- include code to turn help resource into one or more local files
- include code that is a simple web server which makes your help resource available
as a set of URL pages.
