I'm working on the n'th application locating zip's. Everything works fine in PHP while I worked along the docu on OpenGeoDB. Now, I'm trying the implementation on the iPhone-SDK, but SQLite doesn't have the ACOS, SIN etc funcs.
Can anybody point me to an example of how to expand the SQLite with userfunctions in order to use them in a select?
Any hints appreciated!
Thanx and happy coding!
Marcus
This one clears it up pretty nicely:

sqlite3_create_function(database, "yourAwesome", 4, SQLITE_UTF8, NULL, &yourAwesomeFunc, NULL, NULL);

I am trying to create a table using
knitr::kable(head(mtcars[, 1:4]), "simple")
knitr::kable(head(mtcars[, 1:4]), "pipe")
Although this should work according to https://bookdown.org/yihui/rmarkdown-cookbook/kable.html,
it just returns could not find function "kable_pipe".
knitr::kable(head(mtcars[, 1:4]), "html")
and
knitr::kable(head(mtcars[, 1:4]), "latex")
work perfectly fine.
Does anyone know why?
So I had the same problem as this and figured out the problem is that the default knitr install needs to be updated. I think knitr is installed for Rstudio usage. Maybe it uses an old version?
Anyway solution is to do
install.packages("knitr")
and then restart R. Should work after that.
I have a problem when I tried to integrate tiki with my LDAP server. In the test_ldap.php I wrote the code to debug according to this website (https://doc.tiki.org/LDAP%20authentication). This code returned a success. So I know that my LDAP is working fine. I have a problem at
$entry = Net_LDAP2_Entry::createConnected($this->_ldap, $this->_entry);
In the shiftEntry function in Search.php. When I return debug in here, it goes to ClassLoader.php and it go to
register_shutdown_function(function () {
TikiLib::events()->trigger('tiki.process.shutdown', []);});
In my opinion, maybe the problem is the
spl_autoload_call
The spl_autoload_call function called Net_LDAP2 which extends PEAR somewhere before this line in Search.php. This would lead both Net_LDAP2 and PEAR and PEAR_ERROR... Then when it comes to Net_LDAP2_Entry class, it would also load PEAR.... Would this create a fatal error?
I keep having blank screen in my tiki. Tried to cut the code from Search.php to the test_ldap.php to test. It has the same problem.
I am using:
Version 16.2
OS: Clear OS
Thanks for your help. I am blocked now.
I think this may be a good start: https://dev.tiki.org/item6283. If you look in the comments by albertgi he states changing some function names in PEAR.php. I was having LDAP integration problems and this was one of the key problems.
I am wanting to display the album artwork of a song (accessed via the taglib-sharp library) within a Windows Forms picture box. The problem I'm running into is that the taglib-library returns an image of type TagLib.IPicture whereas the picture box requires an object of type System.Drawing.Image.
I have scoured the internet for many hours now, looking for a way to convert from an IPicture to Image, but to no avail. The best lead I have is this: http://msdn.microsoft.com/en-us/library/system.windows.forms.axhost.getpicturefromipicture.aspx, but I have yet to see a successful example of how to implement this.
Any help as to how to convert between these two types would be much appreciated. Note: IPicture is not analogous to IPictureDisp in this case.
I've done the opposite before - turning an existing .jpg into an IPicture for embedding in an .mp3 file. I just tried reversing that operation and, after tweaking and testing, came up with this:
TagLib.File tagFile = TagLib.File.Create(mp3FilePath);
MemoryStream ms = new MemoryStream(tagFile.Tag.Pictures[0].Data.Data);
System.Drawing.Image image = System.Drawing.Image.FromStream(ms);
Thanks for the question - I already know how I'm going to use this myself!
Update: Here's the other way (.jpg to IPicture that I've done before):
tagFile.Tag.Pictures = new TagLib.IPicture[]
{
new TagLib.Picture(new TagLib.ByteVector((byte[])new System.Drawing.ImageConverter().ConvertTo(System.Drawing.Image.FromFile(jpgFilePath), typeof(byte[]))))
};
Ok...I give up :)
What is the best way to select values out of a GWT Suggest Box using
WebDriver? I'm using FirefoxDriver, and so far nothing seems to pick
values out of a GWT suggestBox...not sendKeys, not selenium.keyUp,
anything.
I've even tried executing javascript directly to get those values to populate, like this (to no avail):
((JavascriptExecutor) driver).executeScript("document.getElementById('spSelect').value='verizon'");
Is there a better
way? If not, what is the "best" way to get values out of a GWT suggest
Box?
Many thanks in advance.
Cheers
Pedro
Ok, we've figured out our problem.
We were setting explicit IDs on our elements, so our tests can grab
them easier. In GWT this is done via:
usernameLabel.getElement().setId("consoleLoginPageUserNameInput");
This works fine for most GWT inputs, but for the SuggestBox it is
handled a bit differently:
spSelect.getElement().getElementsByTagName("input").getItem(0).setId("spSelect");
After grabbing the correct inner table, we are able to interact with
this input with Selenium just fine. Hope this helps someone.
Cheers
Pedro
Try this javascript (from here):
To set the value:
document.getElementById("spSelect")["value"] = "verizon"
To retrieve it:
var value = document.getElementById("spSelect")["value"];
So I need a few simple pointers with the BIRT chart API.
I am trying to draw a simple line chart of a numeric value over time. I have a vector of (Date,Double) pairs as input. I have read through the examples in org.eclipse.birt.chart.examples but not yet gained enough traction with the API to start making use of it. Just composing a org.eclipse.birt.chart.model.impl.ChartWithAxesImpl has me stumped.
The eventual destination is an Eclipse editor, and that I can do. Is there a tutorial or book anyone can recommend that might get me going with the BIRT chart side?
I should be very grateful
M.
Well. There is this example: http://www.eclipse.org/articles/article.php?file=Article-BIRTChartEngine/index.html
But I am having some problems actually getting it to work myself. All I end up with is an exception like this:

I had the same trouble with the examples from org.eclipse.birt.chart.examples. There are some good java code snippets, but you do not see to what they correspond. This is why I decided to generate all the examples and put them on a web site: BIRT Charts Gallery.
