Processes an AppPage with the special tags embedded within it. The processed AppPage will be returned in a buffer.

Example

returnCode = WebExplodeToBuf(cntrlHandle, myAppPage, "param1=3600", buffer);

Syntax

int *WebExplodeToBuf(void *controlHandle, 
		char *appPage,
		char *variableList,
		char ** buffer)

controlHandle	The handle to the control structure.
appPage	The handle to the AppPage. Use the value returned by wcLoad( ).
variableList	A supplemental list of variables for the current call to WebExplode( ). Variables in the list are specified as name-value pairs, separated by ampersands (&), as follows: name1=value1&name2=value2[&name=value]...
buffer	The buffer where the exploded AppPage is kept.

Returns

0	Successful AppPage explosion.
Error code	Failure or exception. For a list of possible error codes, see Error Messages.

Program Example

The following code shows how WebExplodeToBuf( ) is used in an application.

int main(int argc, char **argv)
{
	wc_t	*wcp;
	int	ret;
	char	*newbuf;
	int tempNo = 0;
	
	char *pagePtr ;
	char *pgID ;
	char *dbname, *dbuser, *dbpass;


	if((ret = wcInit(argc, argv, &wcp)) != ERR_OK) {
		return wcTraceWarn(wcp, ret);
	}

	/*Get Input from file InputFile*/
	GetInput(wcp);

	while (1) {
		if((ret = wcConOpen (wcp, 0)) < 0) {
			if (ret == ERR_MSGSHUTDOWN) {
				wcDBClose (wcp, wcAppPageConnName(wcp)) ;
				return wcExit(wcp) ;
			}
			return wcTraceErr(wcp, ret);
		}

		if ( (ret = wcGetVariable(wcp, "$MI_SERVER", &dbname)) != 0 ){
			return wcTraceWarn(wcp, ret);
		}
		if ( (ret = wcGetVariable(wcp, "$MI_USER", &dbuser)) != 0 ){
			return wcTraceWarn(wcp, ret);
		}
		if ( (ret = wcGetVariable(wcp, "$MI_PASSWORD", &dbpass)) != 0 ){
			return wcTraceWarn(wcp, ret);
		}
		if ( (ret = wcDBOpen(wcp, wcAppPageConnName(wcp) /*connName */, dbname, dbuser , dbpass)) < 0) {
			return wcTraceWarn(wcp, ret) ;
		}

		}
	
		wcDropVariable(wcp, "$MIval");

		if(newbuf != NULL)
