Hello!
I want to draw points and lines in a picturbox previously loaded with an image. (C#.NET 2k3)
I am trying to do something like drawing a red point where I click on the image. I do this, for example, in the MouseUp event, but nothing happens:
Graphics graph = Graphics.FromImage(pictureBoxHM.Image);
graph.DrawEllipse(new Pen(Color.Red),400,400,400,400);
pictureBoxHM.Update();
Any clues, please?
Thanx in advance!

It's amazing to me how many people continue to use a picture box when they move beyond what it's designed for. Why not just keep a bitmap in memory, and draw it yourself ?

Hi there!
I'm developing an application with C#.NET 2003 and I want to use a web service I just created on the same computer to test it.
What I've done is to add the web reference (called "localhost" as default). Now I want to declare an instance of that service "localhost.Service1 s = new localhost.Service1();"
but the code preprocessor can't see it. When I try to compile it tells me a reference might be missing, but I actually added it.
I tried to create a new project, and it does add it correctly. Why in my application it doesn't? It's a windows form app.
Help, please! 
NOTE: I just observed that localhost namespace is different! How can I change it????

Hello sergestusxx,
I think there is no problem in ur application. Only thing is make sure that how you are adding the web reference.
When you adding web service url in web reference dialog box, botton right corner there you have to mention the proxy namespace Name(suppose ttt), press OK.
go to your code there
ttt.Service1 s = new ttt.Service1();

HI, i've explained my problem earlier - http://codeproject.com/script/comments/forums.asp?forumid=1650&fr=26&select=1320834#xx1320834xx.
Here it's briefly. i have an assembly that is put there:
http://195.234.68.210/Test/index.html
http://195.234.68.210/Test/ImageEditor.dll
I add the code group to the "Runtime security policy" node in .Net configuration 1.1 applet
like it's discussed here:
http://www.developer.com/security/article.php/11580_3483866_1
But my applet still requests for the permissions: UIPermission, WebPermission
while it was already added.
This page will be given to many users - and i will probably need to give them deployment package or whatever. but still i can't tune this to fun on 1 pc
How should I trust this assembly?
Thanks for help.
I'm also ruzzled-duzzled. in the exception box it's shown PublicKeyToken=b77a5c561934e089 failed.

Hi all:
I'm developing Smart phone demo project, but I encounter some problem as follow:
The compiler complains about the following code, for
" Error 1 error LNK2019: unresolved external symbol lstrlenA referenced in
function "wchar_t * __cdecl _com_util::ConvertStringToBSTR(char const
*)"
"
But I don't know how to fix it!
int COlog::CreateXml(char* strFileName, char* strTime, char* strRes)
{
char m_szPath[MAX_PATH];
MSXML::IXMLDOMElementPtr Root;
Root = m_pDoc->createElement("RunInfo");
m_pDoc->appendChild(Root);
MSXML::IXMLDOMElementPtr Res;
Res = m_pDoc->createElement("Result");
Root->appendChild(Res);
Res->Puttext(strRes);
MSXML::IXMLDOMElementPtr Time;
Time = m_pDoc->createElement("Begin");
Root->appendChild(Time);
Time->Puttext(strTime);
_snprintf( m_szPath, sizeof(m_szPath), "%s.XML", strFileName);
_variant_t varString = (m_szPath);
m_pDoc->save(_bstr_t(strFileName));
return 1;

Hi All,
From my system, I want to stop / start the IIS of different machine and that machine may be on different domain. I have written the following code, it works for my system and it does not work for othe system. It would be great help if you can give some idea.
private bool IISReset(bool start, string machineName)
{
string arguments = string.Empty;
if (start == true) arguments = machineName + " /start";
else arguments = machineName + " /stop";
try
{
//setting the password
System.Security.SecureString pw = new System.Security.SecureString();
char ch1 = 'm';
pw.AppendChar(ch1);
ch1 = 'd';
pw.AppendChar(ch1);
ch1 = 'm';
pw.AppendChar(ch1);
ch1 = 'f';
pw.AppendChar(ch1);
ch1 = 't';
pw.AppendChar(ch1);
ch1 = '@';
pw.AppendChar(ch1);
ch1 = '1';
pw.AppendChar(ch1);
ch1 = '2';
pw.AppendChar(ch1);
ch1 = '3';
pw.AppendChar(ch1);
string domain = "MyDomain";
Process process = Process.Start("iisreset", arguments, "maaz", pw, domain);
process.WaitForExit();
return true;
}
catch (System.Exception ex)
{
return false;
}
}

How can you stop other machine's IIS? This is not possible unless until you are able to run this code on the desired machine.
|
|
|
|
|
IISReset command supports to stop/start the IIS which is running on other system. We have tried it on the same network, but there is some problem when we tried to stop/start IIS on different domain.
It is our project requirement, we have to upload some files and before that we have to stop that IIS.

Does anyone here happen to know of any code that will shorten a path stored in a string?
I have found tons of examples using a StringFormatter that all seem to be centered around drawing the the text using GDI+ but I am not interested in that right now. I don't want to roll my own label control at this point, just try to put a long path into one 
I will have to build one myself I guess...
(unless some nice person happens to know where one is by the time I get home )

Hello,
I've written a reflection app. When I run it on some machines it issues a method invocation error. After some checking I've discovered that the problem is that the Windows EventLog is "full."
But I don't care about the event log and I have zero code that refers to it. How do I tell my app to disregard the eventlog? Is there a global setting somewhere?
Thanks in advance!

Where did you find this little tidbit of information?
All you can do is change the Event Log properties in EventVwr. I don't have any problems with each event log set to "Overwrite events as needed" with a 1024 maximum size for each log.

Hi all,
I have a "Managed Extensions" assembly written in VC++ (Visual Studio 2003 - VS7) that so far was build for .Net framework 1.1 customers.
Since all the other assemblies developers in my project already moved to Visual Studio 2005 (VS8) with .Net framework 2.0 , and they want to reference my assembly as "project reference", I have to upgrade the prj file for Visual Studio 2005.
On the other hand, I need that my assembly will be able to be referenced as "dll reference" for VS7 developers, and will be able to run for .Net framework 1.1 customers.
In the following URL I found the answer for regular (c#) assemblies: http://weblogs.asp.net/israelio/archive/2005/06/08/410811.aspx
Any ideas?
Thanks a lot!
Adi

i think you need to specify the minimum .NET version 1.1 in the <assemblyname>.config file
but still use vs2003 to compile it.

Hi!
I want to draw a Map for a Webgame (C#, VWD 2005 EE). I draw Lands, units...
But unfortunatly the borders of the String are not "clearly", good, drawn, as you can see at the link of the german csharp forum. There is a picture where you can see what I mean.
http://www.mycsharp.de/wbb2/thread.php?threadid=13557[^]
So I create the Graphics Device.
G_WorldMap = new Bitmap(3500, 2000, PixelFormat.Format32bppArgb);<br />
Graphics newBmpGraphics = Graphics.FromImage(G_WorldMap);<br />
So I draw the strings
foreach (Land land in G_Game.Lands.LandsAL)<br />
{<br />
Font font = new Font("Comic Sans MS", 10);<br />
SizeF stringSize = newBmpGraphics.MeasureString(land.Name, font);<br />
newBmpGraphics.DrawString(land.Name, font, new SolidBrush(Color.Black),<br />
new Point(land.CenterX - (int)(stringSize.Width / 2), land.CenterY - (int)(stringSize.Height / 2)));<br />
<br />
font = new Font("Courier", 12, FontStyle.Bold);<br />
stringSize = newBmpGraphics.MeasureString(land.Id.ToString(), font);<br />
<br />
newBmpGraphics.DrawString(land.Id.ToString(), font, new SolidBrush(Color.Black),<br />
new Point(land.CenterX - (int)(stringSize.Width / 2),<br />
3 + (int)stringSize.Height + land.CenterY - (int)(stringSize.Height / 2)));<br />
}<br />
Any ideas ?

Set the graphics objects quality settings before drawing to it: (I used G where you have newBmpGraphics)
Graphics G = Graphics.FromImage(bmp);<br />
G.PageUnit = GraphicsUnit.Pixel;<br />
G.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;<br />
G.CompositingQuality = CompositingQuality.HighQuality;<br />
G.CompositingMode = CompositingMode.SourceCopy;<br />
G.TextRenderingHint = TextRenderingHint.SingleBitPerPixelGridFit;<br />
G.InterpolationMode = InterpolationMode.High;

Thx a lot, it is better now.
There is some "interpolation" at borders from the strings and the polygons, which I want to turn off complete.
A new picture is at http://www.mycsharp.de/wbb2/thread.php?postid=72430#post72430[^]
Do you have a link where I can read (good explained) what setting has which effects ? Example ?

Best I can suggest is to refer to the MSDN help for the valious properties, or do what i did and pay around with the possibilities until you find the combination you like.

Hi
I want to develop an Intelligent Agent in .NET environment. I want to know that is there any support for Agent Technology in .NET like Agelets in Java? If not. Then What can be its possible solution? I am not talking about the user interface like MSAgent control.
Thanks for your time
Bye

What's your definition of "Agent Technology"?? Jade?
If so, then no, there isn't that I can find. But that won't stop you from writing one anyway.

Yes, something like JADE. What other possiblities are there to solve such problem? If someone do not want to write JADE in .NET.
