Hi!
I'm trying to make a C# video player and i need to auto hide the mouse cursor in fullscreen after some time. I've managed to hide it and show it, but i get weird bugs. The longer the cursor remains still the longer it takes to hide it and show it and i don't know wtf is going on  Here's my code:
int mishImobilan = 0;
void MainForm_MouseMove(object sender, MouseEventArgs e)
{
mishImobilan = 0;
Cursor.Show();
}
void ProvjeraMisha()
{
if (mishImobilan < 10)
{
Cursor.Show();
}
else
{
Cursor.Hide();
}
if (Cursor.Position == Cursor.Position)
{
if (mishImobilan < 30)
{
mishImobilan++;
//Cursor.Show();
}
if (mishImobilan >= 30)
{
Cursor.Hide();
mishImobilan = 30;
}
}
else
{
mishImobilan = 0;
Cursor.Show();
}
//testic.testBox.Text = mishImobilan.ToString();
if (mishImobilan >= 10)
{
Cursor.Hide();
}
}
// This is the timer
void tajmerZaNest_Tick(object sender, EventArgs e)
{
ProvjeraMisha();
}
And also, does somebody know where can i get a separate Managed DirectX redistributable installation? I need it for my program but i have December 2005 release with the complete DX redist that weighs about 47 mb, and thats really big. All i need is a couple of managed dx dlls...
Thanks!

Can somebody tell me what font and font size can draw fastest in Compact Framework(like MS San Serif or Tahoma or,...). What's i should choice among them? Thanks

Probably a fixed-width font but I doubt there's much difference in speed unless you do your own calculating of positions in which if you're using a fixed-width font such as Courier New you can optimize the code by making a few assumptions.

I for one, do not have a clue what you are talking about.
Perhaps try asking a question, preferably with a meaningful subject line.

Hello!
In my project I try to use LDAP services via P/Invoke (it's a must . All the stuff worked fine till the certain moment. Now when I need to go thru the object's attributes I just stumble upon the problem that I can't get an attribute other then the first!!! Just because function ldap_next_attribute returns a zero value instead of the pointer to the next attribute in the array. Here is the code:
<br />
private static NameValueCollection WR_LDAPGetAllAttributes(IntPtr pEntry)<br />
{<br />
NameValueCollection nvcAttrVals = new NameValueCollection();<br />
IntPtr pBer = new IntPtr();<br />
IntPtr ppValue;<br />
int iValueCnt=0;<br />
IntPtr pAttribute = ldap_first_attribute(pLDAP, pEntry, out pBer);<br />
while (pAttribute != IntPtr.Zero)<br />
{<br />
ppValue = ldap_get_values(pLDAP, pEntry, pAttribute);<br />
if (ppValue == IntPtr.Zero)<br />
{<br />
nvcAttrVals = null;<br />
return nvcAttrVals;<br />
}<br />
else<br />
{<br />
iValueCnt = ldap_count_values(ppValue);<br />
if (iValueCnt==0)<br />
{<br />
nvcAttrVals = null;<br />
return nvcAttrVals;<br />
}<br />
else<br />
{<br />
string sAttrVal = "";<br />
int ippValue = ppValue.ToInt32();<br />
for (int z = 0; z < iValueCnt; z++)<br />
{<br />
ippValue = ippValue + sAttrVal.Length * z;<br />
IntPtr pVal = Marshal.ReadIntPtr(new IntPtr(ippValue));<br />
sAttrVal = Marshal.PtrToStringAuto(pVal);<br />
nvcAttrVals.Add(Marshal.PtrToStringAuto(pAttribute), sAttrVal);<br />
} <br />
}<br />
}<br />
pAttribute = ldap_next_attribute(pLDAP, pEntry, ref pBer);<br />
}<br />
return nvcAttrVals;<br />
}<br />
here is the origial definitions:
<br />
PCHAR ldap_first_attribute(<br />
LDAP* ld,<br />
LDAPMessage* entry,<br />
BerElement** ptr<br />
);<br />
[DllImport("Wldap32.dll", EntryPoint = "ldap_first_attribute", CharSet = CharSet.Auto)]<br />
private static extern IntPtr ldap_first_attribute(<br />
IntPtr id,<br />
IntPtr entry,<br />
out IntPtr ber);<br />
<br />
PCHAR ldap_next_attribute(<br />
LDAP* ld,<br />
LDAPMessage* entry,<br />
BerElement* ptr<br />
);<br />
[DllImport("Wldap32.dll", EntryPoint = "ldap_next_attribute", CharSet = CharSet.Auto)]<br />
private static extern IntPtr ldap_next_attribute(<br />
IntPtr id,<br />
IntPtr entry,<br />
ref IntPtr ber);<br />
I will appreciate way much if anyone help me. Thank you in advance.

I have a class called Options that I vant to serialize in XML that containes a few variables and a couple of functions. My question is how to access these variables from another class so that I may change their values.
If I just declare the variables " public ", I can't access the from my MainForm class (by means of Options.var_name). If I declare them " public static ", I can access them via Options.var_name, but I get an error when trying to assign them a new value.
Any suggestions are welcomed. (Sorry if this is a stupid question, I'm a beginner.)

What does this have to do with seraialization?
Anways: what is the error message you get?

This code works. So how are you trying to access the static variable?

The problem is not in your static variables.
But in the checkBox_Options_CopyToClipboard.

I am using Crystal Report in a C# application. The report size that I have used is A4. The report is getting printed properly on a A4 size paper. But some users they want to print the same report on paper size smaller than A4 size (because the printer is a small printer). The problem is that when they want to print it in a small size paper, a part of the report is getting printed. I want the report/printing area to be adjusted based on Printer Selected.
Is there any way to do so. Please help.

It's a C# Win Form application and Crystal Reports are embedded to it.
|
|
|
|
|
some of your user have to print another format from A4 and you have to use CrystalDecisions.CrystalReports.Engine.ReportDocument
In you form where user gives format of paper, ur application takes that parameters.
example:
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
.
.
.
ReportDocument dc = new ReportDocument();
dc.PrintOptions.PaperSize = PaperSize.PaperA5;

Hello,
I asked this question in visual studio forum too.
Is it possible to move the obj directory ? (like VC++ project)
I would like to have three different directories (on the same root) :
- binaries
- source code
- temporary (obj)
I see where are these options in VC++ project settings, but not in VC# project.
Thank you
Freg.
