I haven't figured out the cause of the problem yet but I was able to get around it. I noticed the .resx for the installer was not found. I happened to have recently removed the existing one to let it re-create it. I restored the resx and it now loads in the designer.

Hi all,
I have two .NET assembly(one library and one WinForm exe) , which i am going to release to the external world. I do not want the public methods of my library to be consumed by anybody other than my exe. Is there an elegant way of doing that?
Regards,
James

You could always apply a licence to the dll and only allow access to methods if the consumer honoured the licence.

You could make all the classes internal and declare your exe as a friend.

How protective do you want to be? You could have the assembly require that certain information be supplied by the calling application before it would work. If the code simply uses a "have things been validated" check, it might not be too hard to bypass, but if some magic constants play a key role in the operation of your assembly you could store them encrypted and use some type of cryptographic handshake with your main application. Unless the assembly and application are both adequately secured against reverse-engineering it will be possible for someone with access to both to reverse-engineer what's going on, but it would be considerably trickier than bypassing a simple validation check.

hi
value returned from the API GetSystemMetrics(SM_NETWORK) is always 3 for me.
Wat does it mean
i have seen fromthe msdn that the SM_NETWORK is used to identify whether the system has network connection or not. Least significant bit is set if the system has network coonection or else it will clear that bit.
but i am gettign value as 3.. What is the reason for it ?
thanks

The only bit that's documented is the least significant. Other bits in the return value may or may not be set, but there is no documentation on what they mean.

Hey guys, what's up?
I have this web service I wrote which works perfectly fine when run on Windows Server 2003 with SP1. However, when I run the same thing on Windows Server 2003 with SP2, I get "Method not Allowed" 405 http error.
Anyone knows what might cause this?
Thanks,
Lior

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.
