I want to format a CString string in a currency while typing in a edit box using VISUAL C++ ... but I can't find a solution which works definitely...
typing for instance the first digit (i.e. 5), in the edit box it must appear 5,00 , typing the second digit 50,00 (the cursor must always be before the comma)... typing 56234 it must be 56.234,00 , typing the , the cursor must go after the comma position and it mustn't appear twice or more times of course... and writing i.e 5,65 it must appear 5,65
This is my code, but it doesn't work perfectly:
there's a variabile CString testo and a variable valuta which controls the edit box
void CCampovalutaDlg::OnEnChangeEdit1()
{
// TODO: Se si tratta di un controllo RICHEDIT, il controllo non
// invierà questa notifica a meno che non si esegua l'override della funzione CDialogEx::OnInitDialog()
// e venga eseguita la chiamata a CRichEditCtrl().SetEventMask()
// con il flag ENM_CHANGE introdotto dall'operatore OR nella maschera.
// TODO: Aggiungere qui il codice del gestore di notifiche del controllo
CString str = _T("0123456789");
CString comma = _T(",");
UpdateData();
testo.Replace(_T("."), _T(""));
if (testo.GetLength() > 3) testo.Insert(testo.GetLength() - 2, _T("."));
double cur = _wtof(testo);
if (testo.GetLength() == 1) testo.Format(_T("%.2f"), cur);
if (testo.FindOneOf(str) != -1) {
for (int i = testo.GetLength() - 6; i > 0; i -= 3) {
testo.Insert(i, _T("."));
}
}
UpdateData(FALSE);
valuta.SetSel(testo.GetLength() - 3, testo.GetLength() - 3);
}
Thanks for solving my problem
If I press the , it appears and the testo.Format doesn't make it appear a comma but a dot. And I can't type the decimal digits :-(
I'm using the library bcm2835 1, it works, I can see on the terminal how plots 126 data information from a sensor but from that point on I recieve this:
bcm2835_init: gpio mmap failed: Cannot allocate memory
Does anyone know what is the problem or how to solve it?I think it's due to the library but not sure how to solve it.
I'm using SPI for reciving the data
#include <bcm2835.h>
#include <stdio.h>
char n = 0;
void escriure_csv(char valor){
}
int main()
{
FILE * fp;
fp = fopen ("file.csv", "w+");
for(int i=0;i<130;i++){
bcm2835_init();
bcm2835_spi_begin();
bcm2835_spi_setBitOrder(BCM2835_SPI_BIT_ORDER_MSBFIRST);
bcm2835_spi_setDataMode(BCM2835_SPI_MODE0);
bcm2835_spi_setClockDivider(BCM2835_SPI_CLOCK_DIVIDER_1024);
bcm2835_spi_chipSelect(BCM2835_SPI_CS0);
bcm2835_spi_setChipSelectPolarity(BCM2835_SPI_CS0, LOW);
uint8_t send_data = 0xB3; //ens dona igual perque nomès ens interesa el que torna
uint8_t read_data = bcm2835_spi_transfer(send_data);
//printf("Read back from SPI: 0x%02X.\n", read_data);
//transformem al que volem
//els canvis seran mV per lo tant enlloc de *2.5 hi fem fer 2
uint8_t mV = (read_data*250)/1024; //en cas que tornes un 0 es perque el resultat es - o 0.
printf("mV: %u\n", mV);
n+=1;
fprintf(fp,"%d",mV);
fprintf(fp,"\n");
//escriure_csv(mV);
}
fclose(fp);
return 0;
}
As one of the comments said the problem here was that I was initializinf the SPI every iteration, I had to put it outside the for loop.
It happens that I have a database connection called Hana (Hana DB) with the programming language Go (Golang). Using the Iris framework.
What happens is that Go has problems with null data. You have to use special data types in the struct as (using the sql library that comes by default when installing Go) sql.NullString
The question is, I have a GetEmployeeData () function called when connecting to a certain URL and returning a JSON. The problem is that it does not return anything, a CONNECTION error REJECTED appears and in the console it prints an error:
hdb.protocol 2018/07/13 16:31:06 option.go:120: type code tcNull not implemented exit status 1
The code was already tested in another SQL call in another function and it works, but this SQL I suppose that when returning 1 only Null or more it gives error.
The code is the following:
func GetEmployeeData(ctx iris.Context) {
const (
driverName = "hdb"
hdbDsn = "hdb://SYSTEM:manager#62.28.253.218:30015"
)
//db, err := sql.Open(driverName, hdbDsn)
//Crea una abstraccion de conexion a base de datos pero no conecta
//Si no que prepara todo para la conexion
db, err := sql.Open(driverName, hdbDsn)
if err != nil {
log.Fatal(err)
}
//Declaramos variable de QUERY
//var peticion = GetCompanyData()
//fmt.Println(peticion)
// var companyData = GetCompanyData()

If someone wants to download the library in their Go folder this is the command:

This is your Github link: https://github.com/SAP/go-hdb
Does anyone know how to fix the error?
Your error is complaining "I don't know how to read a null value."
The options.go file's read function has a switch statement at line 117 that implements the ways to read various database types. You will need to update this switch statement to be able to handle a null ("tcNull"?) type value.
I'm new in SystemVerilog and I would like to verify the value inside generate memories.

You can run your testcase in GUI mode (cadence) and probe all memory. Than look in to memory viewer. You can easily debug memory data using memory viewer.
You can use -gui command line option to run in GUI mode. Than create probe by going in to design browser and select your memory and right click on it and create probe.
I have a little problem with EDSDK.
I tried to make a function that can switch from liveview to movie record.
Everything is fine with liveview, I can take picture.
But when I want to start movie record, I have a ERR_DEVICE_BUSY everytime I want to change a property (save to camera instead of PC). I try everything, make a loop, nothing. And it's the only place where I get this error.
Here's my code :
EdsDataType dataType;
EdsUInt32 dataSize;
EdsUInt32 enregistrement;
err = EdsGetPropertySize(camera, kEdsPropID_SaveTo, 0, &dataType, &dataSize);
err = EdsGetPropertyData(camera, kEdsPropID_SaveTo, 0, dataSize, &enregistrement);
EdsUInt32 saveTo = kEdsSaveTo_Camera;
if(enregistrement != kEdsSaveTo_Camera){
err = EdsSetPropertyData(camera, kEdsPropID_SaveTo, 0, sizeof(saveTo), &saveTo);
if(err != EDS_ERR_OK){
printf("Erreur de changement d'emplacement de sauvegarde, arret de l'enregistrement\n");
printf("err : 0x%X\n", err);
return err;
}
}
//Changement du mode de prise de vu
EdsUInt32 mode = 20; //Le monde 20 correspont à l'enregistrement vidéo
EdsSetPropertyData(camera, kEdsPropID_AEMode, 0, sizeof(mode), &mode);
//Variable pour la mise en route et l'arrêt de l'enregistrement
EdsUInt32 debutEnregistrement = 4;
EdsUInt32 finEnregistrement = 0;
err = EdsSetPropertyData(camera, kEdsPropID_Record, 0, sizeof(debutEnregistrement), &debutEnregistrement);
if(err != EDS_ERR_OK){
printf("Erreur lors du lancement de l'enregistrement");
return err;
}
//Wait for stop record
err = EdsSetPropertyData(camera, kEdsPropID_Record, 0, sizeof(finEnregistrement), &finEnregistrement);
if(err != EDS_ERR_OK)
printf("Erreur lors de l'arret de l'enregistrement");
//L'enregistrement est fini, vérification des evenement
EdsGetEvent();
If you have solution, I take, thanks.
Regardless of what the docs say, the EDSDK sometimes returns EDS_ERR_DEVICE_BUSY for EdsSetPropertyData() when the actual error is a bad input parameter. For example, try setting kEdsPropID_Av with a value of decimal 50 (0x32) which is not in the table given in the documentation. On my EOS 5Ds, this returns EDS_ERR_DEVICE_BUSY no matter how many retries are attempted. Passing a legal value, e.g. 0x33 (for f/6.3) succeeds first time. The bug is 100% reproducible here.
So, if you get this "device busy" error when setting properties, check the input values you are passing with a fine-toothed comb.
You can try this I don't know if you already but it should work it has for me so far on all my property changes.
Just after you opened the session use the EdsSetPropertyEventHandler function
Begin by stopping you LiveView by putting kEdsEvfOutputDevice at TFT if I recall good. (the parameter that is not PC).
In the call back of the property event handler you make a switch on the event and when it is for the property kEdsEvfOutputDevice, then you throw your function to go to movie mode.
the callback function will be called when the property changed will be made so you won't have any device busy or notready. But becareful you have to set your callback function to static so that it works. So you wont be able to call anyother functions that the one that are static, the same for the variables.
If you didn't understand I can explain it to you in french, far more easy for me ^^
