• .NET Development WMI wireless signal strength

  Hi, I have searched everywhere for the answer to this question with no luck. Question: I have 4 Access Points on my network, and I want to get the signal strength of device X which is connected to my network. However, I need to get the signal strength of device X in relation to each Access Point. Can this be done with WMI I have managed to execute a WMI query which gives me the signal strength of connected APs, but this does not seem to give me the relationship between an AP and a device on the network. If WMI is the wrong solution, then how can this be achieved Thanks Heaps, Patrick. I too am interested in this. Perhaps it could be achived using wmic and grabbing the output from the command line (a bit like usi ...Show All

• Visual Basic How do I make this flicker-free?

• Windows Forms NumericUpDown, Binding and the tab key

  I'm using .NET Framework 2, Visual Studio 2005, and Windows Vista RC1. When you type a new value in the NumericUpDown control, and then you leave the NumericUpDown by clicking another control, the NumericUpDown fires events in this order: 1. ValueChanged 2. Validating But when leaving the NumericUpDown by pressing the TAB key, events are fired backwards: 1. Validating 2. ValueChanged And with this, a Binding to the Value property, if it has DataSourceUpdateMode=OnValidation, does never update the datasource. The Binding object handles the Validating event of the control, and, if its value has changed (if the control has raised ValueChanged before), the binding writes the value to the datasource. But if ValueCha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Microsoft.Xna.Framework.Storage Namespace Classes

  Are the StorageContainer and StorageDevice classes not implemented fully or at all The methods for the classes don't seem to be static and there's no constructor defined to create and instance of either class I've not tested this at all but a quick look suggests that you use those classes something like this: StorageDevice sd = StorageDevice.ShowStorageDeviceGuide(PlayerIndex.Any); StorageContainer sc = sd.OpenContainer("SpacePigs"); Cheers, Leaf. ...Show All

• Windows Forms Connecting to a Web Service

  Our Client Application needs to connect to a webservice, which is in the same solution, different project though. I can do it perfectly on my box, and it works, however, it's defauled to "localhost". All of our customers have their own sub-domain for their site. Example: Customer1.OurSite.net Customer2.OurSite.Net ... Customer532.ourSite.net And so on. So... When they first run this application, I ask them to input their website address, which I save to an XML file. This way that client will be set to lock-onto that website. How do I tell my application to point the webservice to Customer1.ourSite.Net instead of localhost Theoretically I want to change the settings in that XML file 10 times in 10 minutes and have the application hit each ...Show All

• Visual C++ Strange 'new' behavior

  Consider the following code: int** a = (int**)new int[][2]; // compiles ok int** b = (int**)new int[]; // compiles ok int** c = (int**)new int[2][]; // generates C2087 If I'm interpreting CPP2003 correctly, none of these are valid, as the expression inside the []'s is supposed to be a constant integral expression, which I doubt the empty expression is. In any case, why do the first 2 compile but not the 3rd If you have a chain of []'s, they're supposed to look like [expr][expr]...[expr][pos-const]. Your explanation discusses how arrays are accessed, and I agree with you on how the array access is done with pointer arithmetic. Your explanation also does make sense as to why #3 can't possibly be implemented. ...Show All

• Smart Device Development Compact Framework 2.0 Install Problems

  I have an iPAQ 2795 with Windows Mobile 5.0. ActiveSync has never worked for me, that is a separate issue. For this reason I install all programs on it by first obtaining a .CAB. I put this .cab into a .zip and post it to my local website. From there I use pocked ie to download. I exctract this zip on my mobile device with functionality built into the Resco File Explorer. I have verified that Resco is extracting files without issue from a .zip. With the .cab file on the mobile device I simply double click and the install starts. Everytime I do this I see the following message: "Installation of CF.cab was unsuccessful". CF.cab is file "NETCFv2.wce5.x86.cab" simply renamed. Using cgacutil.exe I can see that Comp ...Show All

• SQL Server [HELP!] How do you make the database path relative in the connection string?

  Hi everyone, I am working on a Hospital Information System project with a team of 6.Each one of us builds or modifies a part of the system and shares the project over a common repository. The problem here is that we use the absolute path of the database in our connection string. Although the directory structure of our project is the same for each member, since the main project folder itself is stored in different locations on each person's computer (for example, one may have it stored in c:\My Documents and the other in d:\ My Documents), we are forced to modify the connection string manually each time someone else from the team updates the repository with the database. How do we make the path of the database relative so that we don't h ...Show All
