events - Gray out a form row's (detail's) button conditionally with VBA code -

-

I have a standard form in MS-Access that lists a set of orders, and the order number , Customer etc. Fields + Notes and a button to see attached document files.

On request from our customer, let us select two other tables from two questions (one should check or uncheck the button btnAnm (depending on the calculation) The check field is empty and is a check).

I have tried btnAnm_BeforeUpdate (...) and BTNANmbrereenderer (...) and put breakpoints in all, but none of them Not triggered if I use the Orderner control instead of btnAnm , then there is only one.

Set me every " me. " (line), and set properties of the control of the row in that sub.

What do I do? I have seen the help file and searched here.

* Edit: So I want to do something that was not done "to do this"? To wit. Incident incidents have not started in the details as an alternative, do I base the value of a checkbox on each line on a query based on the 'Orderner' field of the existing row and the result of the blank number from another table and the blank field check Can i do

Am I based on the list in such a query, or can I tie additional checkbox fields in a query?

A description of how to do it (a COUNT and a coalition "is not empty" Yes / No for checkbox value) will be completely acceptable, I think! :) *

You can not do much in an ongoing form with an unbound control, whatever They only apply to the current record, you can use a bound control with a click event so that it can work as a button.

Possibly related documents are the reference to the order number that appears on your form, which means that you can create a control, we call it CountOrders, such as a ControlSource: < > = DCount ("OrderID", "QueryName", "OrderID =" & [OrderID])

Controls can be hidden, or you can use the text box You can set it to correct or incorrect return, you can also use it for conditional formatting, but the duration From somewhere, the command not to buttons. Expression is [CounterOrders]> 0

You can also hide the content and add one click event, which will replace the command button Works conditional formatting will allow you to enable or disable textboxes.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
