Where inst is the pointer originally passed to RemoteDllSetReceiver buffer & size contain the notification text as defined in the Remote Protocol. Note: notifications may arrive in different threads (e.g. network, timer, audio).
I can't imagine what i mus do with on_received_buffer_t, must it be a delegate? Like you can read, this functions returns notifications from the DLL like connection status, user id...
I am trying to convert a DLL function call which has the Callback function routine called within the DLL function call.The DLL function call signature is like this:
I am exposing some ISO C++ data types to .Net (mono on Linux to be precise).For the purpose of brevity, I shall refer to C# in my question, although my question relates to all of the .Net languages (with C# and VB.Net being my target languages). So far, I have worked out how to expose the ISO C++ data types in C# class(es) for use in mono -The only problem so far is how to deal with the C++ callbacks. In .Net languages (C# and Vb.Net), I believe 'delegates' are the callback equivalent.
Sticking with C# for now, can anyone recommend a way that I can register the C# delegate functions with my ISO C++ code.The ISO C++ code is a notification library, and I want to be able to "push" the notifications to the mono framework (i.e. C# delegates in this case).My underlying assumption is that the mechanism/steps to implement this would be the same for the .Net languages - I'll just have to code the actual delegates in the .Net language of choice - is that assumption correct?Last but not the least, is the question of thread saftey. The underlying ISO C++ code that I am exposing to .Net (mono to be more specific), is both re-ntrant and thread safe - do I have to do anything "extra" to call .Net delegate from my ISO C++ code?
I was trying to use the System.Threading.Timer to run a function every 250ms - but I'm finding it difficult to cancel the timer from within the callback function. I can't seem to find a reference to "this" (js has this - it's so nice). At any rate - how could I start a callback running 250ms from now - without a timer - and then if I want to continue it again do another start for 250ms.
only code I can find after several hours of searching is a PHP function. Although I can more or less see what's happening, I'm not able to convert everything. The main problem is the "temp_getBytes" function. I don't know how to convert that.I already have the file as a byte array, because it was decrypted, so I'm writing the byte array to a memory stream in order to work with the data. I've added a bunch of question marks where I'm having a problem converting the code.
I'm using a SQL Server database and a bindingsource, and i want to filter a numeric field in order to, for instance, when I write 1, the grid shows all the rows in which that field begins whith 1 (1,10,14...). In order to do this, I have to convert the field to varchar, but VB shows an error message when using cast or convert functions. I have this sentence in my
I have this function that maps a IDataReader to a class. It is obviously written in C#. My co-worker wants to use the same method in his code, but he is writing in VB.net. Basically I am having difficulty rewriting this due to the Lambda expressions used in C#. He is running .Net 3.5.
I don't really understand what the TWriteFileCommand in parathesis after the equal sign is for in that statement. When I try to do it in VB.NET, I keep getting errors because I can't get a reference to the CreateCommand function. The closest I've gotten is this:
Dim MyAppBase As OPSupport.App.AppBase Dim writeFile As TWriteFileCommand writeFile = MyAppBase.CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile)
However, I have a green underline after the equal sign @ MyAppBase that flags an error "Variable MyAppBase is used before it has been assigned a value. A null reference exception could result at runtime."What am I missing? Why in the C# code is the instance fine and what do I need to get the equivalent instance in VB.NET?
I am new to vb.net and would like to be able to convert the following code to it's own function - either inside the current module or better yet in a seperate class.This code currently runs in the KEYPRESS event and ensures only numbers, decimal point, 2 decimals etc. are entered and not letters. Works exactly how I want it but would now like it in a function.I need this code in numerous text box controls but I would rather just call it somehow with a function.
I have a very old app that uses a little function that calculates a value and after that i get the hash code of that value, that it's used as a password to unlock some functionalities to the user. Now the manager has a 64 bits computer and the function returns a different value. What i need it's how to convert this function from C# to Vb, i know that I can use the converts, but they don't work, pointers. Code: Can I convert this function?
I have a function in VBA that I need to convert into VB.net:Sub Crossfunction(ByVal Array1 As Decimal, ByVal Array2 as Decimal) As Boolean
Dim C As Variant Dim Above as boolean Array1 = Array(1, 2, 3, 4, 5, 6, 7, 8, 9) Array2 = Array(1, 4, 3, 7, 5, 8, 7, 2, 9)
[Code]...
Is this the correct method? And how can I convert the function and not get an error: Error 1 Value of type 'System.Collections.Generic.List(Of Decimal)' cannot be converted to '1-dimensional array of System.Collections.Generic.List(Of Decimal)' when I redefine the Arrays as: ByVal Array1() as List(of Decimal),ByVal Array2() as List(of Decimal).
I have the code below. The code returns a string in (IntersectingPoints) for X and Y. I need X and Y values to be in single and stored in an array to deal with later.[code]...
I have a window that I need to activate and the window name does not work in AppActivate("WindowName") because this does not work with partial captions etc... and the window name will be different depending on user. That being said I am able to use "GetwindowhandlefromPartialCaption" to retrieve the # value of the window name or handle. Is there a way to convert this or extract the name from the handle ID to use with AppActivate?

I am creating a program that will convert Celsius to Fahrenheit and visa versa. The program must use a function to return the answer. I'm using a string function that will return either the temperature in Celsius or Fahrenheit or "Please enter a valid temperature" if anything but a number is entered. TryParse is used to check if the input is valid.
When using the TryParse method in the function I am trying to use a parameter to pass the variable that will store the converted data type value [Code] The line " If Double.TryParse(tempTextBox.Text, scale) Then " is supposed to check if the conversion is possible and if it is pass either F or C as a variable to the scale parameter. It seems to verify the conversion all right but it doesn't actually do the conversion. Why isn't doing the conversion? Both F and C remain 0. I can get it to work by using two more TryParse methods (one in each branch of the If else statement in the function), but I'd rather not do this.
display a Decimal (or double) to elapsed time [h]:mm:ss (hours:minutes:seconds)using vb.net?
example:
if you were to type "1.34666666666667" into a cell in Excel then choose Custom Format [h]:mm:ss The result is an elapsed time of "32:19:12". Using the OADate function only runs on a 24 hour clock so this does not work for longer durations unfortunately...
