c++ - Can i call multiple times JNI_CreateJavaVM? -


I am trying to call two threads witch "DispFrontEnd" function first thread ended, failing to start another JVM Stayed .. ??

tks 

  #include "jni.h" #include & lt; Process.h & gt; #include "Stdafx.h" // DISPATCH check the check bool DispatchThreadCreated = FALSE; If (Dispatchart cutted == wrong) {Handle HD spread; HDispThread = (handle) _biginthread (DispFrontEnd, 0, (zero *) transmission input); If ((long) HDIPPathread == -1) {log.LogError ("Thread Disp frontend returns ******** bg", (long) hdpritread); Log.LogError ("errno", errno); Log.LogError ("_ doserrno", _doserrno); } And {logloc-> LogMethod ("Dispatch Thread Created"); DispatchThreadCreated = TRUE; // aspara que a thread terminal WaitForSingleObject (hDispThread, INFINITE); DispatchThreadCreated = FALSE; // 01_02_2010 logloc-> LogMethod ("Dispatch thread ENDED"); }} If (DispatchtraredCrited == incorrect) {Handle HD Spreadread 3; Logloc-> LogMethod ("3: Dispatch Thread Created"); HDispThread3 = (handle) _biginthread (disprintand, 0, (zero *) dispatch input); If ((long) HDKTTrade 3 == -1) {log.LogError ("3: Return to DispFrontEnd ******** BG", (long) HDScreadred 3); Log.LogError ("errno", errno); Log.LogError ("_ doserrno", _doserrno); } Other {logloc-> Lodge Method ("3: Dispatch Thread Created"); DispatchThreadCreated = TRUE; // Aspera Q One Thread Terminal WaitForSingleObject (hDispThread3, INFINITE); DispatchThreadCreated = FALSE; // 01_02_2010 logloc-> LogMethod ("3: Dispatch thread ENDED"); }} Zero DispFrontEnd (zero * inder) {JNIEnv * env; JavaVM * jvm; Env = create_vm (& amp; jvm); // Tap back on second call ??? } JNIEnv * create_vm (JavaWime ** jvm) {CString str; JNIEnv * env; JavaVMInitArgs vm_args; JavaVMOption option; Options.optionString = "-Djava.class.path = C: \\ Sending \\ lib \\ Run.jar; C: \\ Sending \\ sections"; // Path to Java Source Code vm_args.version = JNI_VERSION_1_6; // JDK version This version indicates 1.6 vm_args.nOptions = 1; Vm_args.options = More options; Vm_args.ignoreUnrecognized = 0; Int rate = JNIKerezWam (JVM, (NIL **) and NV, and VM_ORG); If (Rate End Lt; 0) {env = NULL; Str.Format ("Error! Create JVM, (% d)", ret); // Show it on another call! ? Logloc-> Logmath (str); } Other {str.Format ("JVM% x successfully created!", Env-> GetVersion ()); Logloc-> Logmath (str); } Return env; }

Do you really want to start several JVMs? Can you use - GIT attack content thread (JavaWam * VM, JNIANew ** p_env, zero * thr_args); instead of this?

The only thing I know is that an original thread can not attach two separate JVMs at the same time.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
