User Control Questions Messages   Related Types This message was discovered on ASPFriends.com 'winforms-cs' list. Wenfeng Gao Hi, I created a user control derived from System.Windows.Forms.UserControl. I embedded a DataGrid control to my user control. My user control showed up on a IE successfully. However my user control will not show up in either of the following cases. 1. I add the following line of code to the constructor of my control TcpClient client = new TcpClient("164.90.243.60", 6868); 2. I add a customer column to the DataGrid control. How to get around these? Thanks. Wenfeng Reply to this message...        Stephen Rees Wenfeng ... I know nothing of TCP so I'm only doing trial and error here. Altering permissions to full trust didn't fix it. Changing it to 127.0.0.1 did. Sounds like it has to originate at the IP of where the applet is situated - which ain't going to work if it's being downloaded to various machines via isp dynamic IP assignement. Remember these things are on the client not the server. If you could grab the final IP and slot it in dynamically somehow - but that sounds like a job for Reflection-Emit to me. Note also :: don't put these constructors in the main code, do them under a button so that they are only created when the button is clicked. That way at least you can get the underlying control showing in the web page and then you know it works. It will then display a securtity message. If you don't you get a blank box. (or you handle the exception within I suppose) I'll get back to you on the custom column one.

Microsoft.NET\FrameworkSDK\Samples\QuickStart\winforms\samples\iesourcing\cs You can do it with anything. Create an app using Winforms ... anything you like. Then convert the main form to a usercontrol ( user control is better than control because you can see it in the designer). Then compile to get errors - you'll need take out AutoScaleBaseSize and the Main function. Then go to project properties and compile as library. That dishes out the dll. Then the html looks like <object id="simpleControl" classid=YourControl.DLL#YourControl.TheControl height="300" width="600" > </object> where YourControl.TheControl is the namespace of the control. You can then open other forms from within that control. Easy - and they're cool 'cos the web page background shows through between the buttons ! I want to build whole websites with it ... basically shove a client app in a web page ... it's faster data access that using html and asp. That's why I have been a bit shocked why data access to an external server requires extra permissions - that then means that the average user has to download and install an msi file - so it might just have well have been an ActiveX control. (java applets can access data on the server with standard security). (( mmm ... Maybe I can do something with streams with Internet permissions - but I doubt it )) When they all went on about ASP, application service providers, this is what I thought they meant ! Silly me.

The're perfect for science co's - you can't do that in a web page. When you do a java applet they cannot be imported into a stand alone app without manually transporting the code and altering it and recompiling. ActiveX needs installing so no one will unless trust is in there somewhere. With these things you can import them straight into an app without modification and they don't need installing on the client. So they could be really neat for displaying scientific/engineering data or plotting cad objects for the public to view. It's a bit of a pity that extra perms are needed to access the server they came from. The apps above generate their own points from code within so it's safe ... but pre-calculated points scan be saved on the server and accessed - we shouldn't really need extra perms for this. Maybe I can access the same IP without restricions, I have been trying with SQLServer that's on a different server. If not, maybe I can do it with streams I don't know - I don't think so. I could write the points in as a parameter but that's cumbersome. I'm going to get stuck into the perms/security and see what I can come up with. So I reckon I talk too much anyway so will leave you for a while till I come up with something new. Suppose it ain't doing the winforms list any harm. i'm mostly talking to myself anyway - it's a bad habit !

I think that IP address is not an issue. I have a working winform app using the same IP address. That IP address is not assigned dynamically. I think that it might be related to .NET partial trust codes. I read Jason Clark's recent article on MSDN, but do not know how to get around it.

Stuff that works from an app doesn't necessarily work from an applet. The stuff that's downloaded is downloaded from the web ... so needs permissions, in case it contains malicious code. If you run it as an app then it automatically has those permissions as you take that responibility when you installed it, or rather double clicked it. You can write an msi file to give an applet those local responsibilities, as soon as you install that msi file it becomes your problem if anything wrong happens with the applet (that's why you can sign them with external people like Verisign or so forth - they tell the people installing them that you are a decent guy) It's a long winded way of saying it but if you double click an exe then if it goes pear shaped then it's your own fault for doubling clicking it - if you install a permission giving msi to give permissions to an applet - then its your fault if it goes wrong. If you run it after downloading it from the web, and it goes pear shaped - then its the software manufacturers fault - i.e. Microsoft. So they make damn sure that they have it signed sealed and delivered the necessary tools to pass the buck ( but it's not passing the buck it's just a necessary way to stop malicious code running rampant - and hats off to MS - they didin't have to produce that sort of security did they ? It's in everyones interest and good on them. Personally I think it could do with loosening slightly in the name of practicality ... MS would disagree. At the end of the day MS have tightened security in this area (more than java) at a cost to the practicality and use of the applets .... i.e. at a cost to the saleable features of dotNET .... I can only take my hat off to them for "doing themselves" in the interest of the publics security. Who can argue with that eh ?)

Support always supported ! PopTimedGrowth is part of .Net I have it as part of Beta2 samples ... the RTM dotNET I have is a free educational version that a mate gave me 'cos his brother works for a college .... And thank God for that ! - unfortunately it had absolutely no examples with it. So I had to load it in on top of the free RTM framework ... that then at least gave me some examples again. Poptimedgrowth is part of the ResourseCD with Beta2 disks. Beta2ResourcesCD\RESKIT\Samples\CS\WinForms-Graphics-PopGrowth If you haven't got this then download from my website at http:// 65.174.82.63/WinForms-Graphics-PopGrowth.exe noting that this is a self-extracting zip file straight from the resources cd.

If what you unpack is Beta2 code you will probably find that all that needs changing is the dispose method :: change to         /// <summary>         /// Clean up any resources being used.         /// </summary>         protected override void Dispose( bool disposing )         {             if( disposing )             {                 if (components != null)                 {                     components.Dispose();                 }             }             base.Dispose( disposing );         } then do the biz to convert to applet. If you want me to do it all for you I will - and supply the dll code in RTM ... I just thought it might be practise, apart from the fact that I don't really know what I've done with it - it 'should' be here somewhere ! Besides .. that's not the best one - the GraphicsExplorer is (check the Mandelbrot) I didn't write this either ( though I have done similar and orginal work in the area of chaos) but I did add the zooming to the original code - which can be found somewhere at codenotebook.com .... Since I added the zoom he has changed his to include a version of that zoom ... I still don't think he's managed/bothered to turn it into an applet - though I haven't been there for a while. He a cool guy - a physicist. Again ... if you can't find or do what you need I'll take a closer look at my system (which itself is pretty chaotic at the moment) and find all the code you need to get the applet working. Cheers Wang. I'm off to bed now, I'm kanackerackereroooooed. :0) Steve. (??? I just had problems connecting to codenotebook.com .... I hope he's ok ????) -----Original Message----- From: Wenfeng Gao [mailto:Click here to reveal e-mail address] Sent: 13 June 2002 19:59 To: winforms-cs Subject: [winforms-cs] RE: User Control Questions Steve, Please do not patronise yourself.

There's a bit more too it and I think you know that. I know I don't really. Assigning permissions to local assemblies, that's where you are isn't it ? I'm afraid you're a bit ahead of me here ( I think most are) I should probably be asking the questions and you should be patronising me ! ( a horrid situation to be in - from this end) Will help if I can.

I think that IP address is not an issue. I have a working winform app using the same IP address. That IP address is not assigned dynamically. I think that it might be related to .NET partial trust codes. I read Jason Clark's recent article on MSDN, but do not know how to get around it.

I know nothing of TCP so I'm only doing trial and error here. Altering permissions to full trust didn't fix it. Changing it to 127.0.0.1 did. Sounds like it has to originate at the IP of where the applet is situated - which ain't going to work if it's being downloaded to various machines via isp dynamic IP assignement. Remember these things are on the client not the server. If you could grab the final IP and slot it in dynamically somehow - but that sounds like a job for Reflection-Emit to me. Note also :: don't put these constructors in the main code, do them under a button so that they are only created when the button is clicked. That way at least you can get the underlying control showing in the web page and then you know it works. It will then display a securtity message. If you don't you get a blank box. (or you handle the exception within I suppose) I'll get back to you on the custom column one.

I embedded a DataGrid control to my user control. My user control showed up on a IE successfully. However my user control will not show up in either of the following cases. 1. I add the following line of code to the constructor of my control TcpClient client = new TcpClient("164.90.243.60", 6868); 2. I add a customer column to the DataGrid control. How to get around these?

I know - sorry m8. It's just I don't know enough about everything and I want to. It plays havoc with my confidence levels. The GraphicsExplorer is here http://www.componentsnotebook.com/notebooks/csharp/canvas2.html It's an updated version I think with the zooming built in ... I haven't seen it yet, methix I'll take a sneak preview also. Regards The new & confident Steve. -----Original Message----- From: Wenfeng Gao [mailto:Click here to reveal e-mail address] Sent: 13 June 2002 19:59 To: winforms-cs Subject: [winforms-cs] RE: User Control Questions Steve, Please do not patronise yourself.
