I've got an XImage retrieved by XShmGetImage function. How can I resize it? Is there any function in X11 libraries to perform this operation or I need to use external library?
HI all!
I would like to insert a hash at the beginning of a selected block of text in VIM (ruby comment). I selected the lines in Visual Mode, but how do I perform the same operation to all lines?
Thank you in advance!
Wondering why a particular binary write operation in VB is so slow. The function reads a Byte array from memory and dumps it into a file like this:
Open Destination For Binary Access Write As #1
Dim startP, endP As Long
startP = BinaryStart
endP = UBound(ReadBuf) - 1
Dim i as Integer
For i = startP To endP
DoEvents
Put #1, (i - BinaryStart) + 1, ReadBuf(i)
Next
Close #1
For two megabytes on a slower system, this can take up to a minute. Can anyone tell me why this is so slow?
I have got a simple MySQL table and primary index (id) is not numbered one by one (1, 31, 35, 100 etc.). I want them to be numbered like (1, 2, 3, 4). Please tell me how to do it. I would also like to point that I am aware of possible consequences of the operation, but I just want to tidy up the table.
Hi,
I seem to not be able to find implementation from the common Ajax libraries (JQuery, mootools, prototypejs...) that would allow the operation of parsing the window.location.href for request parameter. I would expect something like:
$P{"param1"} == "param1_value"
Am I missing something?
p.s. The web does contains implementation examples for such operations
The UPSERT operation either updates or inserts a row in a table, depending if the table already has a row that matches the data:
if table t has a row exists that has key X:
update t set mystuff... where mykey=X
else
insert into t mystuff...
Since Oracle doesn't have a specific UPSERT statement, what's the best way to do this?
MethodInfo mi = typeof(NotifyIcon).GetMethod("ShowContextMenu", BindingFlags.Instance | BindingFlags.NonPublic);
mi.Invoke(notify, null);
This throws the following exception:
{"Exception has been thrown by the target of an invocation."}
With the following inner exception:
"Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on."
If I comment out a line of code that sets the images for the context menu entries then it stops throwing the exception.
Any ideas?

I was wondering if anyone new how to get access the metadata (the date in particular) from jpg, arw and dng files.
I've recently lost the folder structure after a merge operation gone-bad and would like to rename the recovered files according to the metadata.
I'm planning on creating a little C++ app to dig into each file and get the metadata.
any input is appreciated.
( alternatively, if you know of an app that already does this I'd like to know :)
I cannot SSH into my instance - Operation timed out. What could be the reasons why, and what can I do to resolve it? Rebooting normally takes a long time to take effect, and might just makes things worst
UPDATE: It is not about permissions - i can log in normally just fine. I suspect it might be because of memory issues

The windows service I am writing will need to run some processor intensive operations once in a while (sound encoding wav - mp3) on a machine that takes part in real time voice communication (so I cannot just run them any-time).
What would you check (what counters maybe) before running such operation?
Can you point me to any good articles?
Is there a better way of doing this:
val totalScore = set.foldLeft(0)( _ + score(_) )
or this:
val totalScore = set.map(score(_)).sum
I think it's quite a common operation so was expecting something sleeker like:
val totalScore = set.sum( score(_) )
So we have a photo like this
