This works fine for debug compilations. But often the release compilations tend to crash half way through because it cannot find the specified versions of specific files (dlls).
Just a guess. Maybe you set this setting for DEBUG setting and you didn't do the same thing in RELEASE setting.

Thanks for that. Now it compiles. It runs fine too, until it needs to find that particular version of the dll.
So if the program starts okay does it mean my dependancies are okay and the problem is probably with my program? Doesnt VS.NET perform a check of all dependancies before running an application?

The first step is making sur that all projects include project references (not assembly references) to other projects in your solution, which you seem to have done.
Second make sure that no designers are open and that the instance of the IDE was started in the build configuration for which you want to compile. Perform a rebuild.
There is known bugs in VS.NET that have gotten better from 2002 to 2003, but they still exist. Hopefully "Whidbey" (here's hopin' for 2004) will fix this once and for all.
Once more important aspect in large, multi-project solution is to NOT use automatic versioning (using asterisks in the AssembyVersionAttribute). You can loose control quickly of assembly versions especially if you don't always compile the solution as a whole.
In a week I typically compile a solution with over 50 projects (don't ask) a couple times, but I usually only build a few projects for which I'm directly responsible and we control our versioning to facilitate better builds and assembly binding redirections for application updates.
While I still see and get  over the problem you've stumbled on, following these guidelines usually helps.

I'm running the following code, and have run into yet another misshap.
shellFolder is a valid COM object constructed by the ParentInterfacePointer from SHBindToParent. I know it's valid as it returns pointers via other functions, however, this function returns nothing.
The relativePIDL is the value returned from SHBindToParent.
Every time I run this method, mySTRRET is still null (well, IntPtr.zero).
<br />
mySTRRET = new IntPtr();<br />
result = shellFolder.GetDisplayNameOf(relativePIDL,SHGDN_Flags.SHGDN_NORMAL,out mySTRRET);<br />
The method is defined almost identicaly as the one in the tutorial (http://www.codeproject.com/csharp/csdoesshell1.asp), but I'm looking for a ptr to mySTRRET (I don't want the object, i want to forward it to another function):
<br />
int GetDisplayNameOf( <br />
IntPtr pidl,<br />
SHGDN_Flags uFlags,<br />
out IntPtr pName);<br />
This is bothering me because as far as I can see it is set up properly, and it also runs without exception.
Any ideas?

STRRET is a structure, look it up in MSDN, you will need to define this, you can't just declare an IntPtr in it's place.

Here's a puzzle. I intend to send an image (jpeg) to a PHP-Driven website via HTTP POST, using a C# app compiled for the .NET Compact Framework.
So far Its all working apart from one thing, when sending the file, it is created on the server, but is corrupt. I'm positive this is down to the image not being sent in the correct format, but what format is it supposed to be sent?
The method of sending is using a WebRequest object and its RequestStream.
Method = "POST";
ContentType = "multipart/form-data; boundary=AaB03x";
The following HTTP post is sent through the stream.
--AaB03x
Content-Disposition: form-data; name="title"
Content-Type: text/plain; charset=utf-8
Title
--AaB03x
Content-Disposition: attachment; name="file" filename="nexi0001.jpg"
Content-Type: image/jpeg
Content-Transfer-Encoding: binary
contents of file...
--AaB03x--
Now alls I need to do is send the image data with this. Yet I've no idea in what format to send it and thus how to prepare this format on the CF.
Ideas?

I think you have to send it in Base64 format. For the beginning check ToBase64Transform class.

I can't seem to be able to use that class in the Compact Framework, would Convert.ToBase64CharArray() work do you think?

I think no problem with that. You have to tranform to base64. No matter with which function.

Hi  ,
I am currently building a simple serial terminal program. I have used text boxes to view send and received data. But everytime the text boxes get updated, they scroll upto the top most position. This is very annoying because I need to scroll down every time something new is received.
Could someone please tell me how to make the text boxes scroll automatically? Or am I better off making my own text box control? If so where can I find more info on how to do that?
Cheers

Hiya I have a data entry form with a grid control. I want to add a new row to the data grid with the customer details after every entry.
The only way I can do it at the moment is to set up a class of properities and call datagrid.DataSource = aCustomerDetails each time. I think this might be expensive on system resources calling this for every entry.(remember, there could be 100 or 1000's of entries!!)
Is there an easy way to add a new row to the datagrid each time??
Thanks.

You have to add a row to your dataset which is datasource of your datagrid, then it automaticlly added to your datagrid too.

I'm using C# and drying to develop a custom TextBox control. Currently I am simply trying to draw with blue instead of black. I've overriddent the OnPaint method and as long as the TextBox does not have the focus it draws the text in blue as i want it to; however, once you click inside of the edit box, my custom drawing routine no longer gets used. If you then force a repaint (i.e. minimize and then maximize) my code is once again used for the redraw. How do I get the control to use my drawing routine while it has the focus and the user is typing in it? Here is the code I have right now:
#region Custom Drawing Code <br />
protected override void OnPaint( PaintEventArgs pe ) <br />
{ <br />
Brush b = new SolidBrush( Color.Aqua ); <br />
Font f = new Font( "Arial", 12); <br />
<br />
pe.Graphics.DrawString( Text, Font, b, 0, 0 ); <br />
} <br />
#endregion

To do a custom textbox is alot of work, perhaps the RichTextBox can serve u better. Also inheriting from a TextBox wont work, TextBox relies on too much PInvoked code, hence much stuff cant be overriden in the usual fashion.

I'm not really afraid of putting a lot of work into it. And i'm mostly a Win32 API programmer, so PInvoke doesn't really bother me. I'm just new to C#. What I want to be able to do is to draw ontop of the text (i.e. circle a word with the mouse) and I was hoping to develop a custom control to allow this to happen. Do you have any suggestions as to how I could do this? Additionally, have you any idea how the VS .Net IDE does the coloring of keywords. Should I just develop my own control entirely from scratch? Any Ideas are welcome.

Most controls in the .NET Frameworks base class library wrap their equivalent Windows common controls. If you've handled common control messages before, you should have no problem handling this. Just extend the control in question, override WndProc and be sure to call the base implementation (base.WndProc) to let the derived class handle the rest of the work.
There are plenty of examples that do syntax highlighting and there are many ways to do it. A good implementation with open source is SharpDevelop[^], a free C#/VB.NET/HTML IDE with designer support. Take a look at the source for syntax highlighting if you're interested.

That is what I had done. I was attempting to extend the TextBox; however, the textbox does some drawing outside of the paint message, and I don't know what that message is. I understand the grand concept, I just can't figure out what message is doing the redrawing (I mean aside from WM_PAINT).
Regardless, the source code to SharpDevelop is definatly going to help me out a lot. I've looked at the source code for the TextEditor control for it and that should be enough to get me pretty far along. Thanks alot for that link.

Hi,
We have a smartclient application in C#. We don't know the clients resolution or dpi.
I know it is possible to detect this.
But then we want to adapt or forms and fonts to that type of screen.
Do we have to create a piece of code for each combination (resolution/dpi) to adapt font and controls (hight/width)?
Or is there something automatically that can do this for us.
Ex. we wrote all forms and they are very nice on a screen with a dpi=96 and pixels 1024/768. But when we run the app. on a screen with other setting it is like hell.
So, I would before showing a form that we detect the settings and then adapt our whole app. forms for this screen settings.
Maybe build one form that consits of a panel. Call it mainpanel.cs.
And then all forms hire of that mainpanel. ....
I don't know where to start with this problem.
Tks,

Subclassing is not the way to solve this. You'll end up with more problems than solutions because of an overly-complex architecture.
You could simply get - as part of a static call (it really only needs to be obtained once) - the dpi of the screen (or any graphical output device for that matter) and either initially size your controls accordingly (hence not relying on the designers to do the dirty work and re-arrange your code for optimal execution) or call Scale or ScaleCore (inherited from Control, and the last is virtual so you can override its behavior).
To get the dpi (logical pixels), you'll need to P/Invoke GetDeviceCaps since .NET doesn't expose these properties in the base class library:
[DllImport("gdi32.dll")]
private static extern int GetDeviceCaps(IntPtr hdc, int index);
private const int LOGPIXELSX = 88;
private const int LOGPIXELSY = 90;Once you have the dpi (should normally be the same for the X and Y axis) you can do the appropriate calculations and scale your controls accordingly.

Use Hide(); and Show(); methods of Form.
