Hi,
I've created a borderless form which is custom located at point(0,0) (the top of the desktop).
the form size is; height: 26px, width = screen width.
my case is when I open another application (i.e. msWord) the top of the msWord window (Title, Grabbing aria, close, min, max buttons) is hidden behind my topmost form.
How can I setup my form to act like the taskbar; which will not allow the new application window to load behind the bar?
tnx

You need to register your application as an AppBar for this to happen. See this[^] MSDN article and this[^] CP article.

Modern telephones use Dual-tone multi-frequency (DTMF)[^] signals to represent the numbers.
You need to play your message "Press 1 for this, Press 2 for that" and then listen to the incoming signal. You need to processes the signal and determine the low frequency portion and the high frequency portion. You can then determine the number (Keypad[^])
(You should also make sure you handle the case that the user doesn't have a DTMF telephone. There are other methods like pulse dialling, which are rarely used any more, but probably still exist. Just have a default selection if no tones are detected)

I want to get the row index when I hover a datagrid.
I use the mousehover event but can't seem to get the row index since I want to get the rowindex even if the actual row has not been clicked.
Any help appreciated.

Im using a tool by sysinternals that shows me whether a file has a signature and the date it was signed. However, I need the api for C#, so that i can get the same results.
Atm I use cmd sigcheck send the results it to a stream and parse the results, but if i have 1000s of files I need to process.start cmd 1000s of times.
Any help is appreciated.

Sigcheck can check several files located in the same directory. Here is an example: Sigcheck v1.54
|
|
|
|
|
Yes, I use sigcheck quite extensively, and can get all values for any file.
However my question is, I don't want to do it from dos, but use some class helper in c# that will do it for me.
So that when i pass the ProceesModule / FullName it will return me those same values that sigcheck return in a dos command.

Hi everyone,
I have a RTB, it's ScrollBars property is None. So if user types too many characters and characters rich the end of my RTB, he/she can't see some characters. How can I get the Maximum number of characters which my users can see?
Hope you understand
Thank you.

It will depend on the size of your RichTextBox and whether you are using a fixed length font or not, what was the reason for removing the scrollbar?

Thank you for your reply.

It's constant.
smyers wrote: whether you are using a fixed length font or not
Actually not.
smyers wrote: what was the reason for removing the scrollbar?
Actually I want to create a MSWord-like application, when user riches the end of a RTB, I'll create a new RTB and user can type his/her remaining characters in it.
If you (or anybody) have another idea, I'll be glad to hear it.
Thank you again

Why are you creating a new RTB, is it for a new page?
|

smyers wrote: is it for a new page?
Yes, definitely.
Creating a new page instead of scrolling down, it's what I want to do.
You said it depends on RTB and font size. If your RTB's Height was 100pxs (WordWrap is true) and font size was 8 and font-family was Tahoma (is font-family makes any difference?) how could you do that?
Thank you very much.

I don't think this is the best way to do it, you will only be able to use monospace fonts and then you would have to physically count how many characters would fit in the RTB before they reach the end.

hi

please help.
Thanks in advance

I think you have to read the whole file, append the string at required location and then write the whole data again.

Hi Simon,
By using that WMI code creator, i creted that code like this.
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery( _
"SELECT * FROM Win32_Printer where name='HP Color LaserJet 1600'",,48)
For Each objItem in colItems
Wscript.Echo "-----------------------------------"
Wscript.Echo "Win32_Printer instance"
Wscript.Echo "-----------------------------------"
Wscript.Echo "Status: " & objItem.Status
Next
It is not working properly.It is showing the status as "Unknown" or "Ok".
But i want the code for displaying the status "no paper", "low paper" etc.
Regards,
Sekhar Reddy

Actually to get the printer status I'm using the following code.
This code is written in c#
using System.Management;
ConnectionOptions oConn = new ConnectionOptions();
System.Management.ManagementScope oMs = new System.Management.ManagementScope(@"\root\cimv2", oConn);
System.Management.ObjectQuery oQuery = new System.Management.ObjectQuery("select PrinterState from Win32_Printer where Name = \"HP Color LaserJet 1600\"");//
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);
ManagementObjectCollection oReturnCollection = oSearcher.Get();
foreach (ManagementObject oReturn in oSearcher.Get())
{
//PrinterState returns a hex value but I use a string/int value
//
// state value
//------------------------------------------------
// Online 0
// Lid Open 4194432
// Out of paper 144
// Out of paper/Lid open 4194448
// Printing 1024
// Initializing 32768
// Manual Feed in Progress 160
// Offline 4096
string status1 = oReturn["PrinterState"].ToString();
int status = Convert.ToInt32(oReturn["PrinterState"]);
switch (status)
{
case 0:
label1.Text = "Online";
break;
case 1:
label1.Text = "Paused";
break;
case 4194432:
label1.Text = "Lid Open";
break;
case 144:
label1.Text = "Out of Paper";
break;
case 4194448:
label1.Text = "Out of Paper && Lid Open";
break;
case 1024:
label1.Text = "Printing";
break;
case 32768:
label1.Text = "Initializing";
break;
case 160:
label1.Text = "Manual Feed in Progress";
break;
case 1026:
label1.Text = "Document failed to print";
break;
case 1027:
label1.Text = "Printing paused";
break;
case 4096:
label1.Text = "Offline";
break;
default:
label1.Text = "unknown state";
break;
}
this.Refresh();
}
This code is working fine. But the problem is , if the printer is on , then it is returning value as '0'. Even i switch of the power to printer , then also it is returning 0. Here 0 means "online". I want to show the status as "off line", "no paper", "low paper". etc.

Sekhar Reddy
