Executable icon doesn't update when .ico file is changed

April 5, 2017, 6:00 am
$

I'm having a similar problem to this thread, but with my executable file.

 

I have a project in LabWindows 2015 SP1 using Windows 7 Pro.  I created an icon file and set my project to use it by selecting Build -> Target Settings -> Application icon file with Configuration set to "All Configurations".  Later I created a different icon file and changed the target settings to use the new file. 

 

When I build my application, I'm seeing something strange.  The icon that shows up in my Windows folder for the application is the old one, and if I create a shortcut to the application on my desktop, I get the old icon.  But when I run the program, the icon in the upper left corner of my main panel is the new one, and so is the one that appears in the taskbar.

 

I tried the solution suggested in the original thread (deleting the cvibuild.xxx folder), but it didn't help. 

 

I did find another solution -- renaming either the executable file or the folder containing it to any other name causes the icon to change to the correct one.  So this isn't a big problem, but I thought I should report it anyway since the behavior doesn't seem right.

 

If I subsequently rename the file or folder back to the original name, the icon reverts to the old one.

Is it possible to select a specific table cell and have the row and column number returned?

I can't seem to find a function that will do this. I previously used EVENT_TABLE_ROW_COL_LABEL_CLICK to get the column information when a column header was clicked, but now I need the row and column information when a specific cell is selected.

 

Thanks!

这几天一直在研究这个问题，都没有调用成功。

matlab写一个简单的求和函数：

function value = my_add(a, b);

value = a + b;

end;

mex -setup

mbuile -setup

deploytool 分别生成过C library版本和C++ library版本的DLL文件，在CVI中隐式调用和显式调用都没通过。

求高手提供一个可用例程，多谢~

 HRESULT    esito = 0;
 ExcelObj_App  ExcelAppHandle = 0;
 VARIANT    TempVariant;

    esito = CA_VariantSetCString (&MyCellRangeV, "A1:A1000");
    // Get Sheet
    esito = Excel_SheetsItem (ExcelSheetsHandle, NULL, CA_VariantInt(SheetNr), &ExcelWorksheetHandle);
    esito = Excel_WorksheetRange (ExcelWorksheetHandle, NULL, MyCellRangeV, CA_DEFAULT_VAL, &ExcelRangeHandle);
 CA_VariantClear(&MyCellRangeV);
    // Make range Active   
//    esito = Excel_RangeActivate (ExcelRangeHandle, &ErrorInfo, NULL);
 
 while (OratorioEstivo[i].Progressivo != 0)
 {
  CA_VariantSetCString (&MyVariant, Anagrafica[i].Cognome);

  Excel_RangeSetItem (ExcelRangeHandle, &ErrorInfo, CA_VariantInt(i+1), CA_DEFAULT_VAL, MyVariant);
 
  i++;
 }

 esito = CA_VariantSetCString (&MyCellRangeV, "A1:A1");
 esito = CA_VariantSetBool (&TempVariant, FALSE);
 esito = Excel_RangeSort (ExcelRangeHandle, &ErrorInfo, MyCellRangeV, ExcelConst_xlAscending, CA_VariantNULL(), CA_VariantNULL(), ExcelConst_xlAscending, CA_VariantNULL(), ExcelConst_xlAscending,
                          ExcelConst_xlNo, CA_VariantNULL(), TempVariant, ExcelConst_xlSortRows, ExcelConst_xlPinYin, &MyVariant);

iberr = 2[0x2] when using ibwrt() using NI GPIB-USB-HS

I am trying to communicate with an instrument using the gpib library in CVI. I can see and communicate with this instrument in MAX without problems. The instrument is connected to a USB port of the PC using the NI GPIB-USB-HS.  After I create the device using ibdev() when I try to write a command using ibwrt I obtain the following error: Function ibwrt(). iberr == 2[2x02]. Do I need to do something else to being able to communicate with the instrument? Has it something to do with the fact that I am using the NI GPIB-USB-HS adapter? 

 

Thanks in advance,

Manuel

How to delete a tdms & tdms_index file programmable.

I have a tdms and a tdms_index file that I open and display the data on a graph and after which I close.

I then want to delete this file using the function DeleteFile(filename).  I keep getting error -6 access denied. How ever

when I restart the program and go directly to delete the file it works no problem. I stepped through the program to ensure that

I was closing the file before attempting to delete it but I still get the -6 error. Does CVI not release the file until it exits?

Any help would be appreciated.

Bonjour, devant réaliser un programme, j'ai comme tâche annexe de piloter un gyrophare sonore et lumineux par USB lorsqu'un seuil maximum est atteint. Ma question est donc: est-il possible, via LabWindows/CVI, de piloter ce type d'appareil ? Ou simplement activer ou désactiver l'alimentation d'un port USB?
Cordialement,
Matthieu

Hi, I'm french. During my internship, i have to control a light (like the police car's light) thanks to my computer (USB) thanks to LabWindows/CVI. Is it possible ? Or maybe can we start / stop the power on the differents USB ports ?
Best regards,
Matthieu

Excel Report - Save to specified location?

Hi, 

 

I've been using the Excel Report library to generate an excel sheet for a CVI project (CVI 2015). The library is working fine when I load it as an instrument to create new sheets, rename worksheets and change the file name but I can't seem to find a way to tell the sheet where to save it. I'd like to be able to save it to a specified folder so I'm wondering if there a simple enough solution to this or do I need to change approach?

 

Thanks.

TDM C DLL calls work as exe, not as DLL (Error -6204)

Hello all,

 

I was hoping to get some help on creating a DLL (I am using VS2017 but hope people on here might be able to trace or help on the issue) using the TDM C DLL functions.


I had everything working fine but one day the function started returning error -6204 when finding groups, and now I cannot even call the DDCOpenFileEx function without receiving the error.  When compiled as an application, all works fine.  When I change the calls to dll and compile as a DLL it simply returns the error.  Attached is a simple test code trying to simply open and close a TDMS file but when I call from LabVIEW, I cannot get past the error.  

 

I think it might be how I set up the project but want to get some advice.  Attached is the sample code, I can also attach the VS2017 solution if people would like to check my settings as well.  If someone has time to confirm they can get it working, I would greatly appreciate it.

Simple console application on real-time target

Hi,

 

I am looking into creating a simple console application on a real-time target. However, it doesn't seem like it will be as easy as I expected. I noticed in the BIOS that Legacy USB Support is turned off since the Boot Configuration is LabVIEW RT, and there seems to be no way to override that. I was hoping to use the stdlib and fgets or something of the sort, but it seems that will not be an option.

 

What are the options I have as far as implementing this? I just need something simple to read in a line from the keyboard when available. 

 

Thanks in advance, and please bear with me, I'm new to LabWindows/CVI Realtime module.

InsertTreeItem cause fatal run time error

Run into this weird problem.  The inherited code has ~ 10 thousand lines.

 InsertTreeItem(panel, TREE, .............., NULL);

causes crash ONLY in debug version !  not in release version.

The Tree is defined as an "int", the last parameter (NULL) is invalid, so crash make sense.  But ONLY in debug version ?!  How could this happen ?

From customer point of view, don't fix it if not broken (and I am not paid to fix bugs.  It's a hardware upgrade project.);

from developer point of view, I can't debug this file if not fixed.
