Hi.
I'm making an application and have a lot of problems.
First of all, i had trouble figuring out - how to get all the items to lower case.
Ok, i fixed that... but the program doesnt work the way it should.
So, the program should work this way:
You start the app. Then u click the button to get all the files from directory and all subdirectories. This goes ok. Ok, but then, i want to remove all doubles in the list.
If theres a file "BeBack.JPG" the app. should check if there's also "BeBack.PDF" or if theres "BlackWhite.PDF" and "BlackWhite_1.PDF" it should remove both entries from the listbox.
My code doesnt do that  i dont know why It also deosnt remove all .gif files
Where did i go wrong? Please help?
Here's the code:
private void button1_Click(object sender, EventArgs e)
{
string[] fajli = Directory.GetFiles(Application.StartupPath,"*.*",SearchOption.AllDirectories);
string[] VsiFajli = Array.ConvertAll<string,>(fajli, delegate(string s) { return s.ToLower(); });
listBox1.Items.AddRange(VsiFajli);
for (int i = 0; i < listBox1.Items.Count; i++)
{
if (listBox1.Items[i].ToString() == listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4, 4) + ".pdf")
{
if (File.Exists(listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4,4) + "_1.pdf"))
{
string temp = listBox1.Items[i].ToString();
listBox1.Items.Remove(temp);
listBox1.Items.Remove(temp.Remove(temp.Length - 4,4) + "_1.pdf");
}
}
else
{
if (File.Exists(listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4,4) + ".pdf"))
{
string temp = listBox1.Items[i].ToString();
listBox1.Items.Remove(temp);
listBox1.Items.Remove(temp.Remove(temp.Length - 4,4) + ".pdf");
listBox1.Items.Remove(temp.Remove(temp.Length - 4, 4) + "_1.pdf");
}
}
}
MessageBox.Show("Done!");
}
private void listBox1_DoubleClick(object sender, EventArgs e)
{
if(listBox1.SelectedItem!=null)
System.Diagnostics.Process.Start(listBox1.SelectedItem.ToString());
}
private void button2_Click(object sender, EventArgs e)
{
if(listBox1.Items.Count != 0)
for (int j = 0; j < listBox1.Items.Count; j++)
{
if(listBox1.Items[j].ToString() == (listBox1.Items[j].ToString().Remove(listBox1.Items[j].ToString().Length-4,4) + ".gif"))
listBox1.Items.RemoveAt(j);
}
}
private void button3_Click(object sender, EventArgs e)
{
if (listBox1.SelectedItem != null)
Clipboard.SetText(listBox1.SelectedItem.ToString()) ;
}
Thanks in advance.

The code is almost unreadable, please use the <pre> tags and use proper temporary variables instead of calling listBox1.Items[j].ToString() and others a hundred times. Also, did you know there's a EndsWith method?

Not until now, i didnt know about ends with. Thank you.
Anyway... yes, the code is a mess here in CP... but still, can sombody give me a clue for a better algorythm or something?

Perhaps you can make a tiny demo and debug the code. That will be faster to find out the problem.

i want to check my modem status every 5 mints.can somebody help with a c# code for that.
|
|
|
|
|
You can use timer object to run method every 5 minutes. As for modem what do you mean by checking it? You can send at commands to the modem.

i want to check mdoem status..status means..i heva lots of AT commands and i want to execute the methos which has all these commands evry 5 mints...can u help me with c#
|
|
|
|
|
You can check current System DateTime and every 5 minutes run your application.
Another way to do this is with a Windows Service.
Best Regards.
|
|
|
|
|
So what's wrong with my first reply? Use timer classes available in .Net Framework to run code every five minutes and use SerialPort class for sending at commands and reading responses.
|
|
|
|
|
Possibly a Windows Service, but a Windows Scheduled Task would be simpler.

Hi all!
Continuing my serial port fight  ...
This time, i'm trying to make sequential Gsm Calls to diferent Gsm numbers. I'm doing some tests, but something's wrong.
My first dial connection is working fine, but when i close it and try to make the next connection, my application turns blocked... and i can't make other dial... Someone could help me with this? The use of filesystemwatcher is only for test purposes.

Hi,
Reposting is bad, but problem is urgent. Sorry for that !
I have a Web Application which referes to COM components for various reasons.
These COM components are built in VB6 and works fine when executed from Windows application from my machine.
This means, COM components are properly registered on my machine. When I gave reference to these from my Web App, respective Interop. DLL are created.
The COM component is the described as - "Microsoft VBUpgrade Tool TypeLib Visual Basic runtime objects and procedures" in VS.NET 2008 reference properties.
Question : I am getting following error when I try to create an object of VBRUN.PropertyBagClass
Error Message : An exception of type System.Runtime.InteropServices.COMException was raised and caught.<br />
Message: Retrieving the COM class factory for component with CLSID {D5DE8D20-5176-4EF2-8581-7B534D2AC56E} failed due to the following error: 80040154.
Stack Trace pointed to the line where object was being created
I searched google and came to a conclusion that I need to give rights of COM component execution for ASPNET account. I tried DCOM Configuration but am not sure to whom give the access rights and of what ?
It would be great if you guys give some sort of pointer to this ? Also wanted to make sure that my conclusion is right ?
Thanks !

You need to write headers in both halves. It's best to use DirectX for this, not do it manually.

public ArrayList MPN = new ArrayList();
public string[,] Modems = new string[,]
{
{"Apple", "Banana", "81563840", "Damson"},

};
public string arrayValue;
private void button1_Click_1(object sender, EventArgs e)

// getphnum();
RoundRobin();
}
private int z = 0;
public void RoundRobin()

if (Modems == null)
throw new ArgumentNullException("Modem");
if (Modems.Length < 0)
return;
//int Count = 0;
int i;
int x = Modems.Length/4;
MessageBox.Show(Convert.ToString(x));
for (i = 0; i < x; i++)
{
string a = Modems[i, 2];
MessageBox.Show(a);
arrayValue = a;
MPN.Add(arrayValue);
}
for (int a = 0; a < MPN.Count; a++)

MessageBox.Show("ARRAY VALUE for index "+a+" "+Convert.ToString(MPN[a]));
}
}
public void getphnum()
{
z++;
MessageBox.Show(Convert.ToString(z));
}
}
}
in this when the getphnum() is called one time i wnat to get firts index value(ie index 0 ph number)ie MPN arraylist.ANd when next time when getphnum () is called i want to get index 1 value from arraylist MPN.(ie the same arraylist from which i call my first array index value)..
can somebody help meeeeeeeeeeee 
|
|
|
|

Take a static class variable and initialize it with the index of array and when you call the method again just add 1 to that variable i.e use that variable like a counter hope this helps sorry for the bad english.
If thats not what you want then let me know

Do you mean a counter? If yes, use "static“ for z var.

I want to create tablelayoutpanel at runtime ..and this functionality same like how this control is doing at design time..like control moving and rows and Columns resizing..How these control is working at design time same like i need to create at runtime.

Create an object to TableLayoutPanel class and add it to your form. Go through the documentation to know what all properties are available. Set them and you are done.
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Hi,
All controls are created at run time and the code for controls that are "designed" within VS resides in the InitializeComponent method of the Form.designer.cs file.
If you are not certain how to write code for a control then just create a test form using the control you want to learn about. Open up the designer.cs file and all will be revealed. The code you would write yourself will be very similar.
