only thing you can do without TLS is to make type library defined API calls You'll see how hard it is to run even limited code without TLS in the "Creating Worker Threads in DLLs" section of this chapter Running extensive VB code without TLS should be called "The Losing Struggle" and left alone Since TLS-less VB is severely hobbled, it's important to know when VB calls TlsSetValue to initialize its thread and project data TLS data is allocated and initialized when the first object is created on a given thread, and it is released when the last object is destroyed The good news is that for everyday VB code, you don't even have to worry about this at all because the only entry points into VB are through ActiveX object-creation (and Sub Main, which is a special entry point) In general, VB code never runs on a thread without an object present on the same thread, meaning that the TLS slots always have valid data So how would you ever get in a situation where VB tried to run code without TLS There is one easy answer to this question: AddressOf The AddressOf operator can be used to hand out an arbitrary function pointer Several API calls tell Windows to use a function pointer as a callback point for an arbitrary thread For example, this happens while creating new threads, system or process-wide keyboard hooks, and NT services Note that DLL modification techniques that expose entry points leave VB in exactly this situation Let's take a quick look at what needs to happen to get a VB DLL to a state in which it can run VB code when entered from an arbitrary function If a function is called in a VB DLL on a thread without TLS, the code is limited to simple arithmetic and type library defined API calls The API call support allows you to use COM API functions to create a VB object The first call is CoInitialize, which establishes or joins a COM STA and enables subsequent Co* API calls You can then use CoCreateInstance against a CLSID in the same VB DLL to create VB object and, hence, initialize all TLS slots At this point, almost everything in the runtime turns back on I've found that MsgBox, InputBox, the App object, and possibly other language features don't work in the immediate function, but everything works perfectly in a called function This means that you should call a helper function immediately after CoCreateInstance The thread state remains valid until you release the initial object After the processing is done, just release your explicitly created object (and any COM allocated locals you may be using), and then call CoUninitialize to balance the CoInitialize call.

The first approach, including the version number as part of the file name, is used in the example projects To provide additional support so that applications can determine the DLL information, DllGetVersion is implemented in all the DLLs; many Microsoft DLLs also provide this callback function as a standard method to obtain version information dynamically The function takes the ollowing form: HRESULT CALLBACK DllGetVersion( DLLVERSIONINFO *pdvi ).Information about the DLL is returned in the DLLVERSIONINFO structure, which contains DWORD fields for cbSize (the structure size), dwMajorVersion, dwMinorVersion, dwBuildNumber, and dwPlatformID The last field, dwPlatformID, can be set to DLLVER_PLATFORM_NT if the DLL cannot run n Windows 9x or to DLLVER_PLATFORM_WINDOWS if there are no restrictions The cbSize field should be set to sizeof (DLLVERSIONINFO) The normal return value is NOERROR Utility_3_0 implements DllGetVersion.

When a user enters the load command in the debugger, the debug engine responds by loading the extension DLL and executing a sequence of function calls on the debugger extension, enabling the extension to perform some preparatory work before accepting commands Similarly, when the debugger extension is unloaded, the debug engine calls an exported function on the extension DLL to allow for cleanup During the debug session, any number of function calls are made by the debug engine to the extension DLL, depending on the action being performed in the debugger The process of loading and unloading the extension DLL and the corresponding function calls is hown in Figure 114.

21 Project 8: The Casio SK-60 Aleatron. .net Vs . Testing. Include barcode code39 on .net using .net vs 2010 . Using the Edit function, have these four samples play s a repeating loop. Turn one of the bending switches on. Nothing should happen yet. If there is a response it s probably because the pot has been wired backwards. If so, just switch the wire going to the outside lug to the other outside lug. With your loop of four samples running and one of the bending switches turned on, slowly begin to turn the pot up. At a certain point the loop will explode into a loud chord effect. When this happens, slowly back off the pot until just before the chord erupts. What you re looking for here is the very slim margin between normal play and the loud chord sound. It s hard to find. Turn the pot back and forth until you find it. When you get the pot set just right, your sample loop will reform into an assortment of unusual compositional structures. You ll find that the slim chance zone can also be accessed by changing the main volume setting when the pot is tuned in the correct range. You can use the volume control as a fine-tuning function in this regard. Experiment with the tempo control, too. You ll find it capable of changing the patterns of the bent music in play. Now go deeper. Experiment with demo tunes, various voices, keyboard interactions, and whatever else you might be able to introduce the bending switches into. Combine switches. Reset the pot. Adjust the tempo again. See what else you can find! There s a lot to discover within the bent SK-60.Related: QR Code Printing ASP.NET , .NET EAN 128 Generator , Create ISBN .NET WinForms

Renaming a Web service requires changing all five occurrences of Service1 Unfortunately when you rename an asmx file in VS NET, it will not rename the Web service class nor will it update the class name in the WebService directive Therefore the easiest thing to do when you create a new Web service project is to delete Service1asmx then add a new Web service from the Project menu and pecify the service name, eg DataService Then open the code view for DataServiceasmx and you should see a class called DataService and an example HelloWorld method that s commented out To add methods to your Web service, simply add a Function or Sub, like you normally would, making sure it is Public and prefixing it with the WebMethod attribute The WebMethod attribute is what makes your methods accessible as operations on the Web service Listing 6-2 shows an example method that returns the server time.
