Sort of defeats the purpose of having a global object it seems to me. I use these to reduce the reads to the Db for static classes/tables and regularly set them to null, I assume this reduces the memory footprint for the object (that's not why I do it but I would assume that would be a consequence).

Read about WeakReference[^] class. MSDN has got an example which will help you to get started. Quoting from MSDN,
A weak reference allows the garbage collector to collect an object while still allowing an application to access the object. If you need the object, you can still obtain a strong reference to it and prevent it from being collected
Other idea is to have a separate thread which looks in the collections frequently and removes the items from it which you don't require.
Edit
You can also create a new application domain for your threads and collections. So when you don't need it, just terminate the application domain and all your resources will get released.

Is it possible to add a Linecap to a GraphicsPath? I've played around a bit and it looks like I'm going to have to change my paths to lines, but I'm a novice so if anyone has a genius workaround it would be much appreciated!
Thanks in advance

Hi,
I haven't done this but I expect all Graphics.DrawXXX() to obey the Pen properties, so I suggest you set StartCap, EndCap (and sufficient Width) to enjoy line caps.
|
|
|
|
|
Just in case you are still having problems, take a look at the application from this[^] link. The app has an option to turn linecaps on/off for the GraphicsPath.
I tried to post this last night, but the servers were misbehaving so I gave up and went to bed.

Thanks.
The problem was that the path did not originally have caps, and so CloseFigure() was used to end the path. Removing this allowed Linecaps to be added, and the Caps automatically close the path anyway.

C#
Crystal Reports
I created a gridview that returns the contents of the the 'reports' directory in my web project. It displays the *.rpt files as links. The links point to an aspx page that contains a <CR:CrystalReportViewer ID="crystalReportViewer" runat="server" />. I am trying to dynamically pass in the reportPath by doing something like this: (report path will change depending on the link that is clicked on)
string reportPath = Server.MapPath("Reports" + Eval("name"));' but when I do this I get an error that states:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. I am new to this and was wondering if somebody could give me an idea as to how I could get the report the corresponds to the link that I click on.

|
|
Try this:
string reportPath=Request.PhysicalApplicationPath + "Reports\\" + name );
where name is the .rpt filename.

Hi thanks for the response.
I tried what you recommended and it did not work. The 'name' is the file name which is in a directory called reports, I get the name from the code below. When I try to pass the name to the Report path it tells me I can do that.
DirectoryInfo di = new DirectoryInfo("C:/Inetpub/wwwroot/ITS_USA/Reports");
FileInfo[] rgFiles = di.GetFiles("*.rpt");
gvReportList.DataSource = rgFiles;
gvReportList.DataBind();
foreach (FileInfo fi in di.GetFiles("*.rpt"))
|
|
|
|
|
Do you receive any error ?
I think the code you use to full the grid is fine.
|
|
|
|
|
Yes, The name 'name' does not exist in the current context.
|
|
|
|
|
Ok I got it,
in this part:
string reportPath=Request.PhysicalApplicationPath + "Reports\\" + name );
You have to replace that with the variable where you have the .rpt file name, I suppose one value from the grid...
Si the result should be something like:
C:\Inetput\wwwroot\myapp\reports\report1.rpt
Where Report1.rpt is the value from your variable.
|
|
|
|
|
Yes that is what I am trying to do.
the variable name comes form the directory info. class. I then want to pass the 'name' of the file precededed by the folder 'reports'. So just like you mentioned it would dynamically create the report path. Hmph. Nothing is ever easy when your new.

Hi,
I have an instance of Bitmap that I want to save as an PNG with Indexed colour mode. How can I do this in .NET?
Thanks,
Steve
|
|
|
|
|
Don't know about indexed colour as I've never had the necessity to do it before and google might help 
but this:
Bitmap bmp = new Bitmap(x,y);
bmp.Save("c:\\bmp", System.Drawing.Imaging.ImageFormat.Png);
|
|
|
|
|
That always saves as ARGB png as far as I know..
|
|
|
|
|
Oh ok. I didn't know
Just tryin' to help
|
|
|
|
|
Hi,
I don't think .NET supports indexed colors for PNG.
This MSDN page[^] says PNG needs 0 bytes for parameters, so there is nothing to choose from.
