Hi there.
I am newbie so please bear with me..
I found a universal remote control application for PDA on this site itself.
The link to the application in C# is below
http://www.codeproject.com/KB/miscctrl/UniversalRemoteControlPDA.aspx[^]
I tried posting comments on the application page but since no one replied for over a month i tried putting my questions here.
1: Is this a "real" universal remote control for all ir devices or just for Phillips ir devices?.
2: How do i run this application? I downloaded the source code and "deployed the solution" using pocket pc 2003 emulator on visual studio 2005 but could not find the application on the emulator....
Please help...
Thanks in advance

Hi,
I have weird problem with SmtpClient class. When I send email using gmail SMTP-server and port 587 it works fine in my own computer but if I install my program to other computer no emails received when I run my program.
Same issue in every other computer. I tried to turn off firewall but still it doesn't work. It doesn't matter what method I use (SendAsync or Send).
Best regards,
Janne Kekki

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 !
