Hi,
I have an issue to run Vision example code Load and Display.prj.
All .lib .h ..etc are included into the project (details in the attached picture) but something is still wrong.
What else is missing?
Thx!

Connecting a trigger pulse from PXI-6683H/PFI1 to PXIe-5172 digitizer
I have a PXI chassis with some digital IO boards, a PXI-6683H IRIG-B board, and a PXIe-5172 8 channel digitizer. I'm using LabWindows/CVI 2017, and trying to connect a trigger from the IRIG board to the digitizer.
I need to use PFI1 or PFI2 on the 6683H as a trigger input. The input pulse is a 60 ns TTL pulse every 50 ms. When the trigger occurs, I need to initiate a 60 us read on up to six channels of the 5172, at the full speed of 250 MSPS.
I can already read the data on the digitizer, I just don't know how to connect the trigger from the IRIG-B board to the digitizer. I've looked at a lot of NISync routines, but didn't see any examples.
Thanks in advance for your help. Any ideas would be appreciated.

ConnectToTCPServer callback in different .c file not working.
Hello,
I have problem with ConnectToTCPServer in my program. Basically i have files scanner.c and scanner.h where ConnectToTCPServer is covered as below:
int EstablishScannerConnection(int scannerHandle, char *ip, int port) {
int status=0;
strcpy (scannerObj[scannerHandle].ip, ip); // kopiuj ip
scannerObj[scannerHandle].port = port; // kopiuj port
scannerObj[scannerHandle].connect = 0;
status = ConnectToTCPServer(&scannerObj[scannerHandle].handle, scannerObj[scannerHandle].port, scannerObj[scannerHandle].ip, TCPCallback, 0, 2000);
if(status < 0) {
scannerObj[scannerHandle].errorMsg = GetTCPErrorString(status); scannerObj[scannerHandle].error = status;
if(scannerObj[scannerHandle].errorCallback) scannerObj[scannerHandle].errorCallback();
else
ErrorMSG( scannerHandle ); } else scannerObj[scannerHandle].connect = 1;
return scannerObj[scannerHandle].connect;
}
also in this file i have got TCPcallback:
int CVICALLBACK TCPCallback (unsigned handle, int event, int error, void *callbackData) {
int status, i;
// szukaj numeru uchwytu
for (i=0; i< MAX_SCANNERS; i++) {
if(handle == scannerObj[i].handle) break;
}
switch (event) {
case TCP_DATAREADY:
scannerObj[i].dataLen = 0;
scannerObj[i].errorMsg = 0;
status = ClientTCPRead (handle, scannerObj[i].data , sizeof(scannerObj[i].data), 1000);
if ( status < 0) scannerObj[i].errorMsg = GetTCPErrorString(status);
else scannerObj[i].dataLen = strlen(scannerObj[i].data);
//scannerGetDataCB(i);
if(scannerObj[i].getDataCallback) scannerObj[i].getDataCallback(handle);
break;
case TCP_DISCONNECT:
CloseScannerConnection(i);
char outputMsg[1024]="0";
Fmt (outputMsg, "Scanner#%d\n\nIP: %d:%d:%d:%d\n\n%s\n\nDisconnected ", i, scannerObj[i].ip[0], scannerObj[i].ip[1], scannerObj[i].ip[2], scannerObj[i].ip[3]);
MessagePopup("Scanner", outputMsg);
if(scannerObj[i].closeConnCallback) scannerObj[i].closeConnCallback();
break;
}
return 0;
}
In main file I have:
#include "scanner.h"
int main (int argc, char *argv[]) {
...
if(EstablishScannerConnection(SCANNER_OP130, SCANNER_OP130_IP, SCANNER_OP130_PORT)) {
SetCtrlVal (panelHandle, PANEL_LED_SCANNER, 1);
} else {
SetCtrlVal (panelHandle, PANEL_LED_SCANNER, 0);
}
}
My problem is that I have got connection with TCPServer by my TCPCallback is not working - i do not have callback TCP_DATAREADY or any different when data is ready. When I put ConnectToTCPServer as below into main it is working (I have callback for TCP_DATAREADY, but TCP_DISCONNECT is not working):
int main (int argc, char *argv[]) {
...
if(ConnectToTCPServer(&scanerHandle, scannerObj[scanerHandle].port, scannerObj[scanerHandle].ip, TCPCallback, 0, 2000)==0) {
SetCtrlVal (panelHandle, PANEL_LED_SCANNER, 1);
} else {
SetCtrlVal (panelHandle, PANEL_LED_SCANNER, 0);
}
}
I am using one thread, and ProcessSystemEvents(); in that thread:
CmtScheduleThreadPoolFunction (DEFAULT_THREAD_POOL_HANDLE, ThreadMain, NULL, &threadMainHandle);
I will be appreciable to give me direction how to fix it.

'General Protection' fault 0x684FE961
Hey,
I am using cursors and displaying annotation in a graph using the following code:
int CVICALLBACK assgraph (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
{
switch (event)
{
case EVENT_COMMIT:
double x,y;
float ox=0,oy=0;
char aminos[20];
if (n < 50 || p == 1) break;
GetPanelHandleFromTabPage (panelHandle, PANEL_TAB, 2, &graphTabPanelHandle);
GetGraphCursor (graphTabPanelHandle, TABPANEL_3_assgraph, 1, &x, &y);
SetCtrlVal (graphTabPanelHandle, TABPANEL_3_X, x);
SetCtrlVal (graphTabPanelHandle, TABPANEL_3_Y, y);
DeleteGraphAnnotation (graphTabPanelHandle,TABPANEL_3_assgraph, -1);
sprintf (aminos, "%c%d-%c%d",seqarray[(int)x],(int)x,seqarray[(int)y],(int)y);
if (x > n-10) ox=ox-3;
if (y > n-10) oy=oy-3;
if (x < 10) ox=ox+1;
if (y < 10) oy=oy+3;
AddGraphAnnotation(graphTabPanelHandle,TABPANEL_3_assgraph, x+ox, y+oy, aminos, 3, 3);
break;
}
return 0;
}
When I press the graph in different locations 10-12 times fast I get the following message:
FATAL RUN-TIME ERROR: "...c", line 463, col 8, thread id 0x00004670: The program has caused a 'General Protection' fault at 0x684FE961.
Strangely, the line RunUserInterface (); in int main (int argc, char *argv[]) function is highlighted - I don't understand why this function even works (is it a bug?), when I tried to put a breaking point there it did not stop.
How can I prevent this error?
Thanks!

Unable to Load DLL's to RealTime Target
Hello,
I am trying to do deploy a code to a realtime Target from CVI, but getting some DLL errors. Before going to the details, here are the system details
- Windows 7 Desktop PC (64bit OS)
- NI Reatime 15 installed on PXI reatime target
- LabWindows/CVI 2015 on Desktop pc
- Microsoft visual c++ redistributable and run time components are installed on the pc
When attempting to deploy the code the following error messages were shown.
after clicking continue in the above dialog, following error appears.
The error on build output says "MSVCP100.dll (also MSVCR100.dll) cannot be copied to target because it could not be found"
if trying to use some daqmx functions, the following error also appears.
I have verified that MSVCP100.dll, MSVCR100.dll and nicaiu,dll are present in the Windows/System32 folder.
what could be the problem? The RT system is fine though when simple codes are deployed.

Assembling a packet from a mixture of chars arrays and an int using Fmt
Hi,
I need to assemble a packet containing 2 qualifier bytes, 2 length bytes big endian, and variable length command bytes.
I can do this in one line and this is what I have come up with:
int Send((unsigned char *command,int port,int length)
unsigned char qualifiers[] = {0xAA,0x55,0};
unsigned char packet[0x10005];
//length is length of command array and stored as little endian on my machine.
Fmt(packet,"%s%c[b2o1]%c%s[t-w*]",qualifiers,length,length,length,command);
To get the 2 length bytes in place with high order byte first i'm using the byte order modifier. Since i'm printing to a string I need to use %c because I don't want the int length converted to ascii. But i need length to appear twice as an argument to fill in the 2 length bytes in my packet.
Is there anyway to get the length in the packet correctly with 1 less length argument?
Thank you

Include File in Build by Configuration
I have a situation where I'd like to build against two different lib files depending on which DLL will be used in the final distribution. LabWIndows/CVI has the ability to Include/Exclude File in Build, but there doesn't appear to be a way to have this change based on the selected configuration.
Is there a way to do this, or could someone suggest another way that I can accomplish this?
Thanks,

Change Project Include Path
Is there a way to change where a CVI project looks for header files through the IDE? The first time I compiled the CVI project the IDE prompted me to direct it to the location of the header file. I created a branch of the project with the header file and want to redirect the path that CVI uses to find the header. The only way I have been able to get it to work is to change the original path which forces the user prompt to direction CVI to the new location.
The header file is not included in the project tree.
The old path is in CVI_includes.txt but is there a way to change that through the IDE?

Tag is moving when text with newline character is inserted
According to the help tags are associated with a given line.
Now I see that tags move a line down if I insert some text which contains a newline...
Let me try to illustrate the observed behavior:
TAG xxxxxxxxxx1
xxxxxxxxxx2
becomes
xxxxxxxxxx1yyyyy
TAG yyxxxxxxxxxx2
Is this the intended behavior? Somehow I find it counter-intuitive, I would prefer tags being associated with the beginning of a line, not with its end.
This line year is ending, may the next bring us many reasons of being grateful.

another way to display tooltips in the UI editor
Hello,
I accidentally discovered an interesting feature:
If you have a tooltip text configured the tooltip usually only shows in the UI editor once you click the 'Operate Tool' button - but it also shows while the 'Edit ...control' popup panel of one of the controls of the respective panel is displayed.
Interestingly the situation is different if the 'Control Coordinates and Dimensions' popup panel is displayed, so I don't think that this behavior is by design but still it is sort of useful

Issue connecting to Barcode Scanner using ConnectToTCPServer
Hello everyone,
I am having a weird issue when using ConnectToTCPServer to connect to a barcode scanner.
The first attempt at connecting will always fail due to a timeout error, but then if I immediately call the function and try again, it connects without issue. I have tried increasing the timeout value to see if that was the issue, but no matter how large I make it, it will always fail on the first attempt.
I am using the same function to connect to a printer, and I am having no issues with that.
Has anyone experienced this issue before or know how I can resolve it?
Thanks!
