hi
I built Software that grabbing weight and throw into open window where the cursor is. Everything worked out well - I only have one problem annoying
Receives a question mark (?) when I open Word. and Then the software hangs not recognize the window properly.
when i open Word i see Word? - 123.docx for example. And even if I remove the question mark, the software is still stuck in this case.
my code:
[DllImport("user32.dll")]
static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);
private string GetActiveWindowTitle()
{
const int nChars = 256;
StringBuilder Buff = new StringBuilder(nChars);
IntPtr handle = GetForegroundWindow();
if (GetWindowText(handle, Buff, nChars) > 0)
{
return Buff.ToString();
}
return null;
}
[DllImport("user32.dll")]
private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll")]
private static extern bool SetForegroundWindow(IntPtr hWnd);
public void Start(string NAME)
{
MSG = lblMSG.Text.Trim();
IntPtr zero = IntPtr.Zero;
for (int i = 0; (i < 60) && (zero == IntPtr.Zero); i++)
{
Thread.Sleep(500);
zero = FindWindow(null, NAME);
}
if (zero != IntPtr.Zero)
{
.
.
.
}
}
what is the problem ? how to fix it ?
thanks

Are you sure that it is a question-mark, and not another character that it cannot/will not display?
[DllImport("user32.dll", CharSet = CharSet.Unicode)]Try to add this attribute to your P/invokes and see if it helps.

i want to return an image from database
i try this code but it give me that error
system.drawing.image.fromstream.(stream bool etc)

Would if some one can solve my problem
byte[] ap = (byte[])(dsetName.Tables[0].Rows[0].ItemArray[2]);
if (ap == null)
{
pictureBox1.Image = null;
}
else
{
MemoryStream mmm = new MemoryStream(ap);
pictureBox1.Image = Image.FromStream(mmm);
}

The error message looks a bit odd since the overload you use uses only memory stream, not any boolean parameters, so check that the row above is really the source of the error.
Also check that the array actually contains elements. For example
if (ap == null || ap.Length == 0)
{
pictureBox1.Image = null;
}
else
{

Generally, faxes need a connection direct to your telephone line - and that is made via a fax modem. It may be possible to send faxes via the internet if you can find a fax sending service but there would almost certainly be a charge for this, probably per page.
Without seeing the code you are using (and MSDN has a heck of a lot of code, so just saying "i used the MSDN code to send fax" doesn't help us at all) we really can't help at all!
But probably, yes - you need a fax modem.

Thanks OriginalGriff,really appreciate your reply,wanna just ask :
after using faxcomexlib and fax modem with direct connection to phone line does will be a charge for this? or it's free even using the telephone line?
|
|
|
|
|
Uhhh...It's just another phone call, so YES, charges apply to whatever phone plan you have on that line.

hey Dave we can send fax using c# for free i mean without phone line or maybe i'm dreaming  ?
|
|
|
|
|

 ok that will save me a lot of time.
Thanks to you all guys.
Have nice day.

A fax is a telephone call as far as the phone company is concerned - so if you can get free calls, you can send free faxes. If you can't, you can't.
That applies to every company that wants to send a fax - so even internet companies have to pay somehow for the phone use.
And you do realise I haven't seen a fax in what: 15 years? How many people do you know that still have one?

You're talking about an entirely different government from the one that exists today.
But, yeah, they have a problem with not having hand-written signatures, something that's difficult to do for most people in an email.
The govenment mantra is "paperwork or it doesn't happen".

Replying here instead of replying to your direct email, as we don't do "personal" fixes.
Have you connected it to the telephone system?

My telephone line is connected to an ADSL modem!and i used the windows 7 built in fax modem 56K is that wrong?
|

Faxes are still phone calls: which means the modem has to be directly connected to the telephone line, you can't use the ADSL connection because that is not on the same frequencies (that's why you need a filter to use a phone on an ADSL-enabled line)

So basically I have a grid
|1|1|1|1|1|1|1|1|
|1|1|1|1|1|1|1|1|
|1|1|1|1|1|1|1|1|
|1|1|1|1|1|1|1|1|
|1|1|1|1|1|1|1|1|
depending on what number is in each grid spot, a different part of the building will be picked, for example 0 could be an empty space, 1 could be a hallway, 2 could be a functioning room like a kitchen or a bedroom.
I basically need an algorithm that would randomize the house while still making it able to walk through, i.e no sealed hallways, dead ends, etc.
I just don't know how to put it in code.
Thank you,
Joe

Well, you need to translate it to simple steps, which are then implemented. Those steps are often referred to pseudo code.
What you want is to "generate a dungeon", one with some specific details. If you search for that topic you'll get a bunch more hits than when searching for architecture
