We've collected a fair bit of code written by different developers, some of who have been lax about disposing Bitmaps after they are done being used. I was wondering if anyone knows how serious a problem that is. Are there any reprocussions to not disposing bitmaps? Won't the GC take care of it all in the long run?

Yes and yes. It uses more memory than is required until the garbage collector gets to it. If you don't dispose of it properly the garbage collector will require two passes at the object (meaning it will stay in memory longer). Also large items, such as bitmaps, go directly into the generation 2 heap which is cleaned up less frequently (meaning it will stay in memory longer).
Bottom line, slap your lax developers.

Actually, large objects will go on the large object heap, which is different than Gen2. Also, the LOH isn't compacted but it is collected everytime Gen2 is collected.

 Looks like I'll have to reread the chapter on garbage collection - I thought Gen2 was the same as the LOH (just synonyms for each other)

No. The tone of the question is too rude for me to be bothered.

Hello everybody,
I want to design only one master page for different type of users. Menu items should display accoding to permission for a user type. To design, i have used menu tool. I want to connect the menu with different sitemaps, because sitemap stores xml data. I will provide all sitemap with different names menually. When someone logging in it will check the user type and set menu items accordingly.
But sitemap datasource by default connect with web.sitemap and shows menu. There is no option found to menually set other sitemaps for a menu.
How can i link with other sitemap at runtime? And how can i design this type of master page? If there is any other process, please tell me.
Please help me.........
Thank you in advance.

You can do this by adding multiple sitemap providers..
1. Add a new provider in web.config (Here XmlSiteMapProvider1 is the new one)
<siteMap defaultProvider="XmlSiteMapProvider" enabled="true">
<providers>
<add name="XmlSiteMapProvider" description="default." type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" siteMapFile="web.sitemap" securityTrimmingEnabled="true"/>
<add name="XmlSiteMapProvider1" description="extra." type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" siteMapFile="web2.sitemap" securityTrimmingEnabled="true"/>
</providers>
</siteMap>
2. You can point different SiteMapProvider to the sitemapdatasource
<asp:sitemapdatasource SiteMapProvider="XmlSiteMapProvider1" id="SiteMapDataSource1" runat="server" startingnodeoffset="0" />

Where can I find online code examples so I don't have to keep refering to my books when I want to check that my code is right? Yes I know, being lazy and what not, but deep down, we all want the quickest shortest route!

MSDN? Alternatively, make use of the code snippets manager in Visual Studio.

I want to be able to take only certain data from a .txt file and display it on my page... the example is this. I want to be able to select all the data inserted in that .txt file where there is a specific date ie. 30 January 2008. Where I have the problem is selecting data that falls across more than one lines in the text file, remembering that the next date is coming up a couple lines later and I don't want to use that data that coincides with that date.
Any advice?
Thanx
Dan

Loop through the file line by line. Take which bits of data you need. Without knowing more about the file structure I can't be of further help.

What if I dont know what data I need? All I know is the date that links me to whatever data coincides with that date. What can I use as a exit from the loop in that case?
example of text:
26 January 2008
Go to Dentist
Eat toast
27 January 2008
Sleep
Write books
28 January 2008
...
and so on...

Being ill at home I thought I'd write you the pseudocode for how to do this.
So this is one of the ways you can do this - just pop the relevant C# in there:
displayline = false
while not readline end of file
if line is date
if date is selecteddate
displayline = true
else
displayline = false
endif
endif
if displayline
display line to screen
endif
while end
You always pass failure on the way to success.

Hi,
I am doing an application in WPF. The application is in maximized state with no minimize and maximize box.However on double clicking over the tool bar, the application got minimized. I have to always keep it in maximized state that would work in all resolutions. Please help me.

You can have the line Me.WindowState = FormWindowState.Maximized in your
Form1_SizeChanged event.

Hai Everybody,
I have a dataset and I am binding the same to a combo box in windows application.
I want a item named "Select" to be in the top and it should be the default one.
Can any one tell me how to add an extra item after binding the combo box with the datasource.
Thanks in advance.
|
|
|
|
|
You can just add it in the form designer and switch on AppendDataBoundItems.
Or you'll have to go with adding it after with ddl.Items.Insert(0, "Select...");
|

|

Thanks a lot.
Actually I have set the text as "Select", but I have forgot to change the drop down style.
Best Regards,
M. J. Jaya Chitra

Why have you deleted your original message? You got an answer to your question, so what's the problem?
It's considered rude to do this.

I am running msinfo32.exe programmatically in my application to output the system information. When this runs especially on windows 2000 sp4, it is scanning the floppy drive and resulting in some noise.
How can i avoid it from scanning the floppy drive?
Thanks.
