Multi-level lists in MS-Word... The new way!?

Okay, it has been a little while now, but each time I just have to search forever to find out how to create a multi-level numbering list.

By default, a list will appear as this:

1. Chapter

    1. Section

        1. Sub-Section

Which may work for you, but in many cases you want to have all the list numbers appearing in your section and sub-sections as in:

1. Chapter

    1.1 Section

        1.1.1 Sub-Section

Okay, so that in itself it actually very easy, but it used to be that you could ...

VTune "New Analysis" button disabled

Yesterday I installed VTune on a system at one of the companies I'm working with. It worked like a charm and I could run a few analysis and see problem areas in the system.

Later I worked on another C++ project in Linux, this morning I woke up on MS-Access, and did a little Drupal after that (PHP). I came back on Visual Studio C++ and... the VTune button is disabled! Not available at all somehow and no error message or anything!?

Turns out, like yesterday I had to start the VTune version of Visual Studio! Without that special version, it simply doesn't work, but it still appears and ...

MS-Access hangs when setting a recordset

Today I experienced a hard lock-up with MS-Access as I was in a form typing a new query.

The new query data is checked first, if valid, then the query is processed and ends in a SELECT SQL order which I save in the Form with a simple OpenRecordset call as in:

sql = "SELECT stuff FROM thing WHERE foo LIKE 'begin*'"
Set CUSTOMER_LIST.Form.Recordset = CurrentDb.OpenRecordset(sql)

That used to work just fine in older versions of MS-Access, but we now use MS-Access 2007.

The hanging happens on the 2nd line, when the Set occurs. Note that it generally happens the second

Too many authentication failures for <username>

Today I tried to make use of sftp to transfer a website to SourceForge.net. Unfortunately, it kept giving me an error:

Received disconnect from <IP address>: 2: Too many authentication failures for <username>

I looked around why that would happen and could not really find anything decisive... until I found an issue in the trac system that SourceForge.net uses. That issue mentioned the fact that the ssh-agent could be the culprit.

It was. Somehow the ssh-agent was sending key after key after key... exhausting the number of keys that SourceForget.net will accept and thus made it

Find Qt version: command line, compile time, run time

Introduction

The Qt library version can be retrieved in all sorts of ways. There are a few I use:

Command Line Version

The Qt tools will display the version. One of the simplest way is to use qmake as in:

qmake --version

It will tell you which version of the Qt library it is using.

When writing a configuration script, you most certainly want to make use of the pkg-config tool (at least under Linux and Cygwin):

pkg-config --modversion QtCore

The result is just the version of the specified module. To find all the available module look in the ...

.change() not working right in Internet Explorer

I had a problem with jQuery and was wondering what could be wrong. Looking around for a solution, it was clear that Internet Explorer is the problem. Not the other way around (As usual.) The thing is that the function works, just not in realtime.

So... I have a Terms and Conditions flag, when you click it, I want to enable the Submit button in the form (by default the button is disabled.)

So I have a function something like this:

var valid = function check_valid() {
  // compute valid
  var valid = ...;
  // assume valid === true if button should be enabled
  ...

Comment spam attack from 109.230.213.100

Network connections

This morning I was attacked by a robot. I quickly noticed that my websites were slow and saw a pretty large amount of traffic on port 80: 208 connections!

Epson 1260 (and others) and Linux

As I started using my Epson 1260 Photo scanner on my Linux box, I got some problems...

The first scan works perfectly, and then on the second and following weird colors start appearing. Usually it is red or green, some sort of a gradient. At times half the page is like that, at times more, at times it's like a gradient...

Searching, some people said that the iscan driver was bad. Not true. The driver works perfectly.

Not too sure where the problem really is, looks like the buffer used to read the data is not correctly cleared before we read the next image. That is, in the video tool I ...

C printf(3) for int, long and long long that works every time

Of Note: This only applies to C99, not C++.

I learned something quite interesting today and wanted to keep a note of it.

Whenever I use a printf() with a format such as %ld and try to compile my code on "many" different platforms, I often get warnings on another one.

The fact is that an int, a long, a long long, an int32_t, int64_t all use a different combination depending on your platform and whether you're running in 32 or 64 bit.

So, the answer to this problem are the #define found in the inttypes.h header file:

PRId8
PRId16
PRId32
PRId64

These entries are used after

The Expression On Load you entered as the event property setting produced the following error: User-defined type not defined

Problem

A few days ago, I made many updates in one of the MS-Access forms I'm working on.

Then, when I tried to open the form I'd get this error...

The Expression On Load you entered as the event property setting produced the following error: User-defined type not defined

This doesn't mean anything to me since I did not define any type... Removing the Form_Load function (commenting it out) made that very error go away, however, since that's the sub-form of another form, it still generates errors when the main form is trying to initialize the sub-form.

Note that it ...
