Try setting each columns header text in the DataGridView properties.

So, you've created the columns, and not AutoGenerated them?
|
|
|
|
|
Nope, columns are all autogenerated, but the header text displays the column name, not the value set in the caption property...and according to help, caption should be displayed.
|
|
|
|
|
The easy way is to make templated columns, and not autogen.

Hi there,
I wanted to start developing some professional looking ui controls ( like these  ) and just can't figure out how these have been developed and I don't want to include images in the project to mimick the look.
Can someone give me an advice where to start or some good links or even books you recommend for this topic?
Sure I know that I can't create such good looking ui controls in a week  I just want a helping hand guiding me into the right direction
Thanks in advance,
Cheers Chris

Petzold [^]covers fundamental topics well. At least he did back when I read him.

Most comprehensive ASP.NET books have at least one chapter on creating server controls, however this book, among others, specifically covers the subject.
Building ASP.NET Server Controls[^]
only two letters away from being an asset
|
|

|
|
Is this book also good if I'm going with WinForms Controls instead of ASP.Net Server Controls ?
|

Thank you!
I will try the first one
Cheers Chris

Hi,
I have created some settings file other than the main Settings.settings within my C# Win project. Before I used to see that, all new varaibles of all other settings files are being saved in the app.config file as an serializable XML. But in the past few days, I faced a problem with Configuration manager and I used to get error message "Configuration manager failed to load". After hassling for a while I found that, once I changed my project folder's name, the "Configuration manager error gone." but Now, I dont see the new variables in the app.config file any more. yet the settings vars are being saved in my computer somehow somewhere... I dont have any idea where are they being saved. I am worrid thinking that, if I ship my software to my client's pc, will it work in the same way by saving the settings variable somewhere in the PC without saving in app.config ?
Thanks and regards
Emran

Each project has a different settings file, make sure you are looking into the right one.
Other than that, as you already know, settings are always stored as XML, cant think of any other place they are stored in.
Hope that helps

Application setting persistence is thorougly described in "Application Settings Architecture" MSDN article (http://msdn2.microsoft.com/en-us/library/8eyb2ct1(VS.80).aspx), though, to say in short, they are stored in two parts: application-scope settings are stored in app.exe.config file that should be in the application folder, user-scope settings are stored in local user profile %InstallRoot%\Documents and Settings\username\Local Settings\Application data\CompanyName\ProductName\ProductVersion. The key thing is that this storage depends not only on product-name but on product build either. So, if you will leave apllication build number as it is set by default (1.0.*) or will change build number yourself location will change after build and your settings will be lost because they automatically migrate only when you use ClickOnce application deployment. Therefore you have to create your own settings migration mechanism or your own custom provider for settings storage to control your settings completely.

Hi,
Thanks for your reply.
I have gone thru the article you provided (MSDN) and I realized that the User Scope application settings are stored in the User's profile path returned by System.Windows.Forms.Application.LocalUserAppDataPath.
Now, it will be an issue to pack this item into a single installer as I am not using "click Once", how can I instruct my application to load and save user scoped settings.config file in the same Application.StartupPath ?
Regards
emran

Well, I'm afraid I cannot be much help to you. I can say that LocalFileSettingsProvider is a bit of a tough job after I looked through its source. It can be reproduced of course but there is a hell lot of work to do.
To be honest I use standard application settings only for a small stuff like window positions - even if they are lost it doesn't make much trouble and can be replaced by reasonable defaults. As for serious things, global settings that persist from version to version and all that I use the same strategy as with common data files - I simply choose the convenient location and put my settings there using simple Dictionary object to store them and serialize/deserialize manually with somthing like SoapFormatter. After all ApplicationSettingsBase is a simple dictionary wrapper too.
Regards, Oleg.

How to download file from FTPsite in asynchronous way?
Please help me.

You can use the System.NET.FtpWebRequest to request files from an FTP site. You can use the FtpWebRequest.BeginGetResponse to do this asynchronously.

Hi,
I am generating product key in the form of ; XXXXX-XXXXX-XXXXX-XXXXX
I want to generate unique serial key related to this product key.
I'd be so glad if someone help me.
Thank you in advance.
|
|
|
|
|
Guid.NewGuid().ToByteArray() will give you 16 bytes.
|
|
|
|
|
But,
GUID will generate RANDOM string, that will NOT related to my product key.
Thank you.
|
|
|
|
|
I don't understand, then, what you're trying to do. You want a product key, I gave you a piece of code to generate one. Are you saying you want to validate that? If so, validate with a server? Or just some special crafted key that is either valid or invalid?
