yes, I'm calling dispose as soon as I don't need them. As I said, the out of memory exception is expected, due to the size of the bitmaps being loaded

Hi,
you may want to read up on the WeakReference class; it allows to hold on to as much data
as possible without ever hitting an out-of-memory situation.

thanks a lot for the WeakReference hint, I've read a bit about it and it looks exactly what I'm looking for!

Hello,
I'd like to Resize a control that contains any text.
If I use TextRenderer.MeasureText there is always a Padding, also if I use the Flag NoPadding:
Size size = TextRenderer.MeasureText("dddd", this.Font, new Size(Int32.MaxValue, Int32.MaxValue), (TextFormatFlags.NoPadding));
I found out that i need to set a IDeviceContext like that:
private void MyControl_Paint(object sender, PaintEventArgs e)<br />
{<br />
Size size = TextRenderer.MeasureText(e.Graphics, "dddd", this.Font, new Size(Int32.MaxValue, Int32.MaxValue), (TextFormatFlags.NoPadding));<br />
}
My Problem is:
I dont want to Resize the Control in the Paint-Event, so I guess I need to get somehow the current IDeviceContext, but how?
Or do I use the TextRenderer.MeasureText method in a wrong way?
Thank You for Your Answers!

Don't forget to dispose of the Graphics object you just created.
It's a very common mistake that leads to resource leaks.

I am new to VS2005 and C# and only involved with desktop programming. I need to email reports to Customers with only IE and Outlook Express. The Pdf file created by exporting from ReportViewer is 1mb. The body of my reports contain tables and line graphs.  Is it possible to do away with ReportViewer and create reports that can be Viewed and Emailed directly from the IE browser. If so what technologies would I have to use eg. Webforms. How do I accomplish this. Thanks

This is a simplified information from the log file on a machine about an unsuccessful setup.
can you see what is wrong?
Please note that the setup does work on some other machines.
ERROR SUMMARY
Below is a summary of the errors, details of these errors are listed later in the log.

Hello,
The first log shows that the activation was for user nguyent and the second log shows that the activation was for nxyz.
Can you please look into this and let me know if this does not resolve this issue.

The above xml file node has so many child nodes named <payment></payment>.
I want the code for counting number of attributes in that node.
I counted the number of nodes in that file as
XmlDocument doc = new XmlDocument();
doc.Load("D:/SAMPLEXML.xml");
int count = doc.SelectSingleNode ("//Payments").ChildNodes.Count;
TextBox1.Text=count.ToString();
now i want to count the attributes in one node i.e payment

You need to check 'Ignore HTML tags in this message (good for code snippets)'

you need to select each node, and do Attributes.Count ( or Attributes.Length perhaps ? ) on the node.

I am currently trying to get Axis IP cameras to identify themselves via the network using C#.
I've captured the packets that Axis' own tool uses and I am trying to mimic them in .NET - without success : (
Apparently the Axis program sends out a Multicast UDP/TCP packet to 224.0.0.251:5353 with the message "_axis-video_tcplocal"
Here's what I captured:
224.0.0.251 MDNS Standard query PTR _axis-video._tcp.local, "QU" question
I've scoured the web looking for a method to do a Domain Name Pointer lookup without any luck.
Any pointers...?
Kind regards - Jakob

How do I convert a string textbox to int?
|
|
|
|
|
int.Parse, int.TryParse or Convert.ToInt32
|
|
|
|
|
Convert.ToInt16(SomeTextBox.Text)
You always pass failure on the way to success.
