What do you mean by a smart client? The asp.net is on the local machine.

A smart client is like half way between asp.net and windows forms :
example[^]
Since its local I would think about the permisions of the asp.net user and the runtime security policy. Perhaps if you give it full permission and full trust and see if that works ?

HI,
I have some 5 lines of text already entered into the text file.
Is there any possible way to enter the next line as the first line and not just append it to the end.
Regards,

You'll have to read the entire file, append your text on the beginning and then write the whole file again.

Try using a StreamWriter to write to your file. The underlying stream, which is accessible through the BaseStream property provides a Position property which should allow you to position at the front of the stream/file.

In short, you cannot INSERT anything anywhere you want in a text file in a single, simple operation. Unless, of course, you want to APPEND to the end of the file.
If you want to insert text as the first lines in the file, you'll have to do one of two things:
1) Open the file; Read the entire contents of the text file into memory; Close the file; Reopen it as a new file; Write out the text you want to insert at the beginning of the file; Write out the contents that you saved; Close the file
2) Rename the file to some temporary name; Open a new file with the name you want; Write out the text you want to insert; Open the temporary file; Read it in, line by line, and write it out to the new file, line by line; Close both files
Method 1 will work very fast is better on samller files. Method 2 will work better for very large files, or files that you can't know the size of ahead of time, or files that exceed RAM capacity, but is slower.

I'm trying to find the most effecient way/most elegant way to do this. I have a Combo box that has a list of network types (all corresponding to System.Net.NetworkInformation.InterfaceType). Now I have an if statement that is dependent on what is selected in this combo box. e.g. if "Ethernet" is selected it will be if(interfaces[i].Type == InterfaceType.Ethernet). Now I know I could just do a massive if nesting but I want to know what you guys think would be best.

It depends what you want to do. If you are just setting a variable or two based on the result, I'd build a hashtable of type to return value, and set it in one line.
Either way, I'd always use a switch over massive if/else blocks.

Basically I am enumerating all of the network adapters on the system and then allowing the user to specify which type to view (only the type selected are shown). It is really only used once.

I reckon the trick is to make the value associated with the strings in the drop down equal the enum value, if that's all you need. Or, better yet, use Enum.Parse to make an enum value out of the string, and use Enum.(whatever the method is that returns a string array from an enum ) to populate it.

Keep in mind that InterfaceType has a backing value type of Int32. My experience with Windows Forms is limited, but if you could get an index value of some type from the combobox, you could cast that value to a variable of type InterfaceType.
i.e.:
InterfaceType selectedType = (InterfaceType) val;
(where val is the index number pulled in through the combobox)
Then you'd only have one conditional statement checking for equality:
if (interfaces[i].Type == selectedType)
Hope this helps!

Good idea... but this is the index list (of all InterfaceTypes)
94 AsymmetricDsl
37 Atm
20 BasicIsdn
6 Ethernet
26 Ethernet3MegaBit
69 FastEthernetFx
62 FastEthernetT
15 Fddi
48 GenericModem
117 GigaBitEthernet
144 HighPerformanceSerialBus
114 IPOverAtm
63 Isdn
24 Loopback
143 MultiRateSymmetricDsl
23 Ppp
21 PrimaryIsdn
95 RateAdaptDsl
28 Slip
96 SymmetricDsl
9 TokenRing
131 Tunnel
1 Unknown
97 VeryHighSpeedDsl
71 Wireless80211
So I cant just do 0 -> 0 1->1 etc

From what I understand about Combobox controls in .NET:
- The Add() method accepts an object as a parameter, and the object's ToString() return value is what actually gets displayed in the Combobox.
- The SelectedItem property returns the object (not the ToString() result) that is selected.
Perhaps it would be possible to create a new struct containing an InterfaceType field, a string field, and a simple ToString() method to make this work. When you use the SelectedItem property of the Combobox to return the currently selected object, you could simply read back its InterfaceType field.
Like I said, I've not used Windows Forms since VB6, so hopefully somebody will correct me if I am in error.
Good luck!

hello,
i have a dynamic control that i add the control collection.
this control is being loaded from ascx.
if i want to change, while postback, the ascx i load, i retrieve a message that i can't since
so what i want to do is to be able to delete control viewstate while postback.
can i do so?
many thanks,
Eran.

I have an imagelist, created in the IDE, and it generated this code for me :
this.imageList.ImageSize = new System.Drawing.Size(23, 23);
this.imageList.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imageList.ImageStream")));
this.imageList.TransparentColor = System.Drawing.Color.Lime;
the second line generates this error:
+ System.SystemException {"Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure \"DetailsActions.resources\" was correctly embedded or linked into assembly \"RDC\".\r\nbaseName: DetailsActions locationInfo: RDC.DetailsActions resource file name: DetailsActions.resources assembly: RDC, Version=1.0.1035.19142, Culture=neutral, PublicKeyToken=null"} System.SystemException
Now, I don't see any way to make the images or the image list build into the assembly, but I don't think that's the problem. I've found some stuff on google, but nothing that's been suggested has helped.
The resourceSets property on the resource object is 0. That is created like this :
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(DetailsActions));
The details actions class is in a subfolder called controls, I've tried adding controls to the path. This project was actually in VB.NET, I just converted it using a tool, but the VB.NET code looks the same to me, and it works.
My default namespace for the project is RDC, the root namespace of the project. Any suggestions anyone can offer are truly appreciated.

The DetailsActions.resources - generated from DetailsActions.resx - was not embedded into the assembly. You won't see this by default in the IDE, so you'll need to go to Project->Show Hidden Files to see it. It should be nested under the form or control to which it's related. The images or image strip that you assigm to an ImageList is base64-encoded into a ResX file, which gets generated into a .resources file and embedded.
If you want to forego the ResX file, then add the images or image list to your project and set the Build Action to Embedded Resource. To create the image or images to add to the ImageList, use something like the following:
Image img;
using (Stream s = GetType().Assembly.GetManifestResourceStream("NameSpace.ImageStrip.png"))
img = Image.FromStream(s);Make sure that "NameSpace" is the fully-qualified namespace of the object you added. So, if your project's default namespace is "RDC" and your image was called "ImageStrip.png" under a folder named "Example", then the fully-qualified manifest resource name is "RDC.Example.ImageStrip.png". Any embedded resources - even .resources files - use this convention unless you explicitly embedded the resources into the assembly (i.e., not using VS.NET or re-assemblying the assembly).

OK, I can see the resx file now, and it's an embedded resource, so it must be in there.
I've inherited this project, the only form in which I have the bitmaps is this project file, where they are embedded in the imageList, with the obvious exception that I cannot get them out. How do I go about turning the list into a collection of bitmaps so I can load them into an image list manually ? Or, preferably, how can I make this code work as it stands ?
If I look at the XML, I can see the image stream there. I've tried all sorts of variations in the path I pass in to the resource object. Is there a way I can query it to find out the path I need ?
Thanks for your help.

The resources object is created like this:
System.Resources.ResourceManager resources = new System.Resources.ResourceManager("DetailsActions", System.Reflection.Assembly.GetExecutingAssembly());
I tried controls.DetailsActions ( because it's in a folder called 'controls' ) to no avail. I've tried various other permutations, and I've also established that all my other image lists ( that reside in the root folder ) are loading fine. I've also reverified that the existing code works perfectly in the VB.NET version. I have no idea what to do next...

The ResourceManager should - if the file "path" in the manifest is the same as the fully-qualified class name - use new ResourceManager(typeof(DetailsActions)).
Make sure the .resources file is in there. Open the assembly in ildasm.exe (installed by the Framework SDK, which is installed with VS.NET by default, into the SDK's Bin directory), double-click "MANIFEST", and search for "RDC.controls.DetailsActions.resources" below the assembly attributes.
