At this point most of us should also receive like a Google MVP award. I mean besides harassing these dim wits it's about the only other thing I do around here any more.

I am writing a Visual Studio 2008 Tool Window plugin that exposes a custom toolbox. I create controls on Forms using the 'ToolboxItem' class. I would like to append to the ToolboxItem dependencies, such that my assembly will be auto-inserted as a reference after the control creation. Here's an example of what I'm trying to do:
ToolboxItem tbi = new ToolboxItem(typeof(CheckBox));
AssemblyName[] depends = tbi.DependentAssemblies;
List<assemblyname> listDepends = new List<assemblyname>();
listDepends.AddRange(depends);
listDepends.Add(new AssemblyName("MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e7d025b3483b4afc"));
tbi.DependentAssemblies = listDepends.ToArray();
The control gets created fine, but 'MyAssembly' is not added to the project references. 'MyAssembly' is installed in the GAC - I've double checked that the full path is correct.
Thanks,
Aaron

AFAIK, this isn't possible. Imagine what would happen if a malicious application injected itself as a dependency into the Form class. Load Form class = load malicious application into memory = bad in one way or another
The best thing you could do would be making a derived class, and add your assembly as a reference

I found this one the hard way, http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=295677[^]. After writing and testing a bunch of code that relied on reading from persisted DataTables one of our test databases had columns with single spaces. While this post discusses .NET 3.0 I am seeing the behavior in .NET 2.0. I have not tested to see if it is fixed in any later versions.
However, if I read the same file, which is still persisted with a DataTable object (DataTable.WriteXml()), into a DataSet object instead and use the first DataTable in the DataTableCollection the whitespace is [appears to be, for me anyway] preserved properly in the DataTable
DataSet someData = new DataSet();
someData.ReadXml("somepersistedDataTable.xml");
DoSomethingToDataTable(someData.Tables[0]);
void DoSomethingToDataTable(DataTable dt)
{
}
Not sure if this is the correct place, or a repost for that matter, but wanted to share just in case someone else was having similar issues.

Hi all,
i am retrieving total physical memory using GlobalMemoryStatus() as follows :
public struct MemoryStatus
{
public uint Length; //Length of struct
public uint MemoryLoad; //Value from 0-100 represents memory usage
public uint TotalPhysical;
public uint AvailablePhysical;
public uint TotalPageFile;
public uint AvailablePageFile;
public uint TotalVirtual;
public uint AvailableVirtual;
}
MemoryStatus stat;
[DllImport("kernel32.dll")]
public static extern void GlobalMemoryStatus(out MemoryStatus stat);
GlobalMemoryStatus(out stat);
uint totPhy = stat.TotalPhysical;
My question is
1) Is the stat.TotalPhysical return the actual physical memory installed int he machine ?
2) I am getting neagtive value like -271691776 for the vista mahcine(Os type : 6.0.6001) and Windows Server 2000 .
Can someone please help me out.Thanks in advance

Hi,
I suggest you switch to GlobalMemoryStatusEx() and MemoryStatusEx (with "long" members)
since IIRC the old ones don't cope with memory sizes beyond 2GB.

On top of what Luc said, you say you got negative numbers?? How?? Since unsigned integers can't return negative numbers, you had to use some calculation that introduced them. This says that your methodolgy is wrong.

GlobalMemoryStatus(out stat);
usrSysInfo.totalPhysicalMemory =(UInt32)IPAddress.NetworkToHostOrder((int)stat.TotalPhysical);
tempArray = BitConverter.GetBytes(usrSysInfo.totalPhysicalMemory);
SysInfoMemStream.Seek(offset, SeekOrigin.Begin);
SysInfoMemStream.Write(tempArray, 0, sizeof(UInt32));
offset += sizeof(UInt32);
I am converting the data to NetworktoHostOrder and convert to byte and trasfer it to the server. Server will do reverse process and get the actual data..
I dont know how the RAM value is in negative.
Similary i want to know whether the GLobalMemoryStatusEx method returns the actuall RAM isntalled in the machine or the RAM available to the users.

Hi,
GLobalMemoryStatusEx returns physical memory, with a few MB deducted for unknown reasons (same thing occurs in Task Manager, it shows 3069MB for 3GB !)

but why its returning negative junk value instead of -1 ???

If a function returns a value you don't like, the most likely cause is you did something wrong. In this case, did you set the Length member of the struct correctly? It is different for
MemoryStatusEx!

i am using like this (in C# code)
stat.Length = Marshal.SizeOf(stat);
because it is not accepting
stat.Length = sizeof(stat);
will it give the correct length of the MemoryStatus
|

if you doubt it, then check it; why would you need or want spoon feeding?
You can see how large the struct is from its definition, and you can watch the value you assign to Length.

sorry , will set the actual value.
why i asked is i tried using Marshall.sizeof function once. it doesnt work proeprly for me. so i took the size by counting the size of every variable in a struct
|
|

sizeof and Marshal.SizeOf may return different values, they do represent different things.
sizeof is the size as a managed object, Marshal.SizeOf is the size when marshaled to the native world.

I knew it was something you did... There's where the negative number is coming from. You converted stat.TotalPhysical to a signed integer, instead of leaving it unsigned.
|
|
|
|

but i am converting NetworkToHostOrder to UInt32 right ??
NetWorkToHostOder accepts only int , long , short of C# datatype. tahts why i have converted it to int.
Oh will the uint to int creates negative value ???

there is a 50% probability they do.
have you any idea how the number representation works?
half of the Uint32 numbers have their highest bit set indicating a value >= 2GB
when looking at the same bit pattern as an Int32 it will be negative.

let me check the server side code and check how these values got converted.
Thanks you to both of you.

I can't for the life of me work out how to implement this in f#
protected override IEnumerable<shapedef> GetShapeDefinition()
{
// Yield out a Box2D shape definition
PolygonDef def = new PolygonDef();
def.VertexCount = 3;
def.Vertices[0] = new Vector2(0f, 6f);
def.Vertices[1] = new Vector2(-2f, -3f);
def.Vertices[2] = new Vector2(2f, -3f);
def.Restitution = 0f;
def.Friction = 1f;
def.Density = 1f;
yield return def;
}
The closest I've come is this
override x.GetShapeDefinition = seq<shapedef>{
let def = new PolygonDef()
def.VertexCount <- 3
def.Vertices.(0) <- new Vector2(1.0f, 2.0f)
def.Vertices.(1) <- new Vector2(-2.0f,-3.0f)
def.Vertices.(2) <- new Vector2(2.0f,-3.0f)
def.Restitution <- 0.0f
def.Friction <- 1.0f
def.Density <- 1.0f
yield (def :> ShapeDef)
}
But I get
No abstract property was found that corresponds to this override. (FS0191) - C:\Users\Matthew\Documents\SharpDevelop Projects\FSharpGame\FSharpGame\Ship.fs:20,14

Got it to work;
override this.GetShapeDefinition() = seq<shapedef>{
let def = new PolygonDef()
def.VertexCount <- 3
def.Vertices.[0] <- new Vector2(1.0f, 2.0f)
def.Vertices.[1] <- new Vector2(-2.0f,-3.0f)
def.Vertices.[2] <- new Vector2(2.0f,-3.0f)
def.Restitution <- 0.0f
def.Friction <- 1.0f
def.Density <- 1.0f
yield (def :> ShapeDef)
}

I have created Abc.msi File using setup and Deployment from Visual Studio 2008. I would like to test this in vertual machine before installing to a client machine. I followed these procedures
1. install .net framework 3.5 on Virtual Machine
2. then install Abc.msi
I gets installed perfectly fine but when I try to open that it Gives me error saying that --
"Abc" encountred some problem. How can I overcome this problem? Any help will be appreciated.
In that winform I have one of the function "print" that prints in Excel file. Vertual machine does have office 2007 installed.
Thank you
bijaya
