I use VS 2005 and C# for only two weeks and I'm desperate in this problem. My program, (screenshot), has two columns with the same content - buttons and textboxes. I really don't know, how to create some simple code usable for both of them. These textboxes and buttons has similar names, like:
textBoxAInput, textBoxAIV, textBoxAIV2, richTextBoxARunda1IVBin; textBoxBInput, textBoxBIV, textBoxBIV2, richTextBoxBRunda1IVBin;
and there are buttons like: buttonTextA, buttonTextB
There is about 20 textBoxes in both colomns.
What can you recommend me to use: I want to have just one general program capable opperate with both columns? ...some delegates, or special classes, some universal usercontrol, maybe interface? I'm begginer in C# and I don't know well these special purpose "things".
The best idea I have is, if possible, using strings as names: pseudocode
void printsomething(char ID)
{
//ID is A or B
string nameIV1 = new string("textBox" + ID + "IV1");
nameIV1.Text = "something"; //any idea, how to use "string as object name"?
}
I don't wanna use unsafe code, so there's no way using references, like:
if (sender.Equals(buttonTextA))
textBoxIV = &textBoxAIV;
else
textBoxIV = &textBoxBIV;
//or is something like that possible in "non-unsafe" code?
any idea, how to do this?
thank a lot for any help.

Hello
I hope i got you right. Two things to mention:
1- If you want to access control by name like you stated use this.Controls["MyControlName"]
2- If you want to make a sinle event handler for several controls, select them all in the designer, then in the PropertyGrid write the name of the method you wish to handle the event in that event's field.
Or in the code write this:
MyButtonA.Click += new EventHandler(MyHandler);
MyButtonB.Click += new EventHandler(MyHandler);
Then MyHandler will handle the Click event in both buttons.
If you need more similar help, or if I missed something, please post more details of what you need.

Re 1: this.Controls["MyControlName"] : I've tested this way now, but it doesn't work. It throws an exception: "Additional information: Object reference not set to an instance of an object." I'm not sure, where's the problem:
String vstup1Hex = "richTextBox" + id + "1Hex"; //id is A
Controls[vstup1Hex].Text = Radix.Stream2Hex(Input, 16, 4); // doesn't work
Re 2: I use one handler for every pair of buttons for some time. But still, in this MyHandler function I have to determine, which textboxes I have to work with richTextBoxA1Bin or richTextBoxB1Bin, etc.

Hello
This exception means that the control with this name is not a memebr of the controls of the form. Two possible problems:
1- What is th id part?? is it a string? Check you casing because names are case sensitive in C#.
2- You've put your control in a container control, eg. GroupBox, Panel, etc... If this is the case use MyGroupBox.Controls[ControlName] instead because the button is a member of the groupBox's controls not the form's controls.
PS.
Don't forget to cast the control into the type that you want if you need to, eg.
if(Controls["MyButton"] is a Button)
{
((Button)Controls["MyButton"]).PerformClick();
}

BTW:
The screenshot link is working now, and I took a look at your form. It's number two. You have to access the control by the GroupBox name.

Yes, I have specified the GroupBox names and now, it works. Thanx a lot!

Does anyone know how to retreive the command line arguments for an existing external process ? StartInfo.Arguments does not contain it.
|
|
|
|
|
Hello
Why, I wonder?? Arguments should be in that property!! Try using the ProcessStartInfo.Verbs property instead.
Regards
|
|
|
|
|
Verbs does not contain any command line args at all. It purpose of use is very different. it indicates the actions that the system can apply to the file indicated by the FileName property of ProcessStartInfo class.

Well do i assume that the external process is a managed app?
Anyways, any process started with command line arguments, has them stored in the process primary stack, since they are in scope of the entry point. You need to write a generic unmanaged code piece to access the string array passed into the entry point by the c runtime in an unmanaged process. For a managed app you need to get the pointer location of the entrypoint and then in contigous to the it would be the command line arguments passed in. you can see where the arguments finish by wrapping your search before any instruction address or jmp instruction appears.
Does that make something clear here?

Hi,
I was trying to close my application but it doesn't work as the Task Manager still showing that it is running. I'd search around the Internet and tried Environment.Exit(-1), Thread.CurrentThread.Abort() but nothing works.
Any idea?
Thanks in advance.

Hello
If your application is multithreaded -which I suspect-, Probably one of your foreground threads is still running. Either keep track of your threads and abort them on exit -or end them more gracefully if possible-, or set them to background threads so that they exit themselves upon the program termination.
Regards

Hi
Thanks, it works, the Task Manager don't show the process any more when I exit the application

Well depends on the CLR. when main returns, main still is the primary thread, but a manged thread. It will depend on whims n fancies of the CLR. CLR will take some time to reflect the thread stoppage, depending on other work it is involved in. So no need to be worried.

Hi
i written code in vc++.And GUI in C#

You could write a C++ DLL and export the necessary functions.
You can then use P/Invoke to call these functions.

You need to give more info on what you need to achieve and the structure of the code. If its a client server application, simply use sockets to transfer information back and forth. Else use C# to consume the DLL created with VC++ through P/Invoke, based on whatever your need is. This will enable C# code to call into the functions defined within your C++ code
Does that answer you?

Hi,
Im having a strange problem which i can't solve.
this is the code:
XmlWriter writer = null;
DateTime dateNow = DateTime.Now;
DateTime timeNow = DateTime.Now;
string test = "testinggggg";
string tessst = "testtetststs";
// Create an XmlWriterSettings object with the correct options.
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.IndentChars = ("\t");
settings.OmitXmlDeclaration = true;
settings.Encoding = Encoding.Default;
settings.NewLineOnAttributes = true;
settings.ConformanceLevel = ConformanceLevel.Fragment;
//dateNow.ToString("dd-MM-yyyy");
//timeNow.ToString("HH:mm:ss");
Console.WriteLine("The date of today = " + dateNow.ToString("dd-MM-yyyy"));
Console.WriteLine("The time of right now = " + timeNow.ToString("HH:mm:ss"));
try
{
// Create the XmlWriter object and write some content.
writer = XmlWriter.Create("Testing.xml", settings);
writer.WriteStartElement("Information");
writer.WriteElementString("DateOfBuilding", ""+dateNow.ToString());
writer.WriteElementString("TimeOfBuilding", ""+timeNow.ToString());
writer.WriteElementString("Testing", test.ToString());
writer.WriteElementString("Whatever", tessst.ToString());
writer.WriteEndElement();
writer.Flush();
}
finally
{
if (writer != null)
writer.Close();
}
Console.Read();
The problem is the date and time are written in the same tag.
This is how it looks like:
<Information>
<DateOfBuilding>9-9-2006 14:51:42</DateOfBuilding>
<TimeOfBuilding>9-9-2006 14:51:42</TimeOfBuilding>
<Testing>testinggggg</Testing>
<Whatever>testtetststs</Whatever>
</Information>
How can i write the date and time in sperate tags?
Thanks in advance!

You may want to consider using DateTime.ToShortDateString() and DateTime.ToShortTimeString().
/ravi
|
|
|
|
|
DateTime dateTimeNow = DateTime.Now;
...
writer.WriteElementString("DateOfBuilding", "" + dateTimeNow.ToShortDateString());
writer.WriteElementString("TimeOfBuilding", "" + dateTimeNow.ToShortTimeString());
Is this okay for you? You don't need two seperate DateTime variables for the same date.
