Hi,
What I have is a main form with several textboxes, one of which is filled by reading from a text file. The main form allows the user to load another form that allows the user to edit the file and then return to the main form after saving any changes.
What I would like is for the main form's textbox to be programatically refreshed when the user returns from the editing form. It's easy to have the user do something (click in the textbox for example) and have it updated but I would like it to happen automajically  .
How can I go about having the edit form tell the main form to update itself when the edit form closes?
TIA for any suggestions.

If you open your edit form by calling ShowDialog simply put the update code behind this call as ShowDialog blocks execution until edit form is closed. Otherwise register an event handler to the Closed event of your edit form and put the update code inside.

You can use OleDb to query the database and get all the rows. Once you have all the rows you can do every thing you nead with them : sorting and filtering (with a dataview) and adding, removing and updating rows through the datatable.
Search cp for articles relating all i've mentioned.

Hi,
I am installing some COM components with my C# application but what really happens is that every time on startup it tries to relocate the components and perhaps register them. How can i set the installer to register those components only once.

Standard Question #1: What is the error?

You have not shown a class, you have shown a single method.
You do not call a .cs file you intantiate classes then call the methods in the class
Might I suggest that you read a beginners book on C# because I get the feeling that if I attempt to answer you it will turn in to a very long thread that could easily be resolved if you just read some introductory information in C#

No, that is standard question #2.
Standard question #1 is:
What do you mean by "not working"?

If you use my standard questions, please use the right ones.
Here is a complete list of my standard questions:
Standard question #1:
What do you mean by "not working"?
Standard question #2:
What error message do you get?
Standard question #3:
What does your code look like?
Standard question #4:
No, "nothing" never happens. Exactly what is happening?
Standard question #5:
No, that is not the code you are using. It can't produce that result. What does the code you are using look like?
---
b { font-weight: normal; }

Hi,
I have made an installer for a windows application. But there is a problem, when i click the icon on the desktop or in start-menu, the application appears to re-install itself ( a progress bar runs fast once or twice) & (here comes the problem) it executes the Custom Action that i have set for the Commit event. It happens every time when i click the icon.
I am also using some COM components ( there names start with AxInterop. & Interop., I suspect they are COM components), is that problem due to these components? Moreover, the persons who are using the computer on which i install my app, they say that they had to re-register their COM components every day after my use.
Please give me some link, help, guidance. I am posting this message for the second time...
Regards,
Wasif Ehsan.

The applicatin reinstals because you have alterated it's root directory and or the binary files, so, the smart and wise Windows Installer reinstals your application. In order to avoid runnting the custom action over and over put a condition to find out weather is a fresh install or a repair - I can't remeber what was the condition.

Hi,
I have created an installer for my C# desktop application. I want my application to startup after it has successfully installed. I dont want to use Custom Actions. How can i do that?

I'm afraid there is no way to startup after it installed but write some code in install script.

Is there a way to monitor the information sent to a specific USB channel and mimic it?
I love to program!
|
|
|
|

The short answer is no.
The long answer is yes, but with extreme difficulty. Requiring something like kernel-level debugging techniques to intercept/shadow calls to the USB driver. AFAIK, there is no way to monitor the serial bus directly.

hi, i built a PVR a few years ago and its running the latest version of GBPVR, and im not exactly pleased with its support for multiple cards (particularly the softwares ability to change channels, theres no effient way to use 1 device to change the channels of the tv, its long and complicated, but its not easy...) in any case, is there a way that i can capture input from a tv tuner card and save it as an Mpeg?

You can try playing with GraphEdit, then use DirectShow.NET. I have not done this myself, but would love to...

From messageboards, it appears BeyondTV has the best multiple tuner support, but thats not free

Do you have some code sample pls
/thx

|

Sure:
CodeTypeDeclaration ctd = new CodeTypeDeclaration("MyEnum");
ctd.IsEnum = true;
ctd.Members.Add(new CodeMemberField("int", "Value1"));
ctd.Members.Add(new CodeMemberField("int", "Value2"));
CodeNamespace cn = new CodeNamespace("MyNamespace");
cn.Types.Add(ctd);
CSharpCodeProvider prov = new CSharpCodeProvider();
ICodeCompiler comp = prov.CreateCompiler();
CodeCompileUnit ccu = new CodeCompileUnit();
ccu.Namespaces.Add(cn);
ccu.ReferencedAssemblies.Add("System.dll");
CompilerParameters cp = new CompilerParameters();
cp.OutputAssembly = "MyAssembly.dll";
cp.ReferencedAssemblies.Add("System.dll");
cp.GenerateExecutable = false;
CompilerResults cr = comp.CompileAssemblyFromDom(cp, ccu);
if (cr.Errors.Count > 0)
throw new Exception("Compile Errors!");
Assembly asm = cr.CompiledAssembly;
Type t = asm.GetType("MyNamespace.MyEnum", true, false);
foreach (string s in Enum.GetNames(t))
Console.WriteLine(s);
