Weird problem, started with migration to Visual Studio 2010.
Some forms, when opened, will have some objects' properties set to a string that is empty in resource file. Most often these are control properties like ImageKey, ToolTipText and for UltraGrid some columns get columnX.Header.Caption set to that string. This will obviously remove set images and give wrong column header texts in other locales. Additionally tooltips will show up in weird places (like tab panel body).
This string (strSaveInterestDetails8 below) is empty in Strings.resx (<value />), but not empty in Strings.fi.resx. When I changed this string to have a space, designer started to use an other "empty" string from Strings.resx..
These forms are all derived from common base, but it does not have anything special/suspicious. Debugging these from additional devenv instance failed, since the debugger never broke on the set breakpoints (thrown exceptions in internal VS code were caught).
example:
ultraGridColumn23.Header.Caption = global::Company.Module.Properties.Strings.strSaveInterestDetails8;
...
this._timespanCheck.ImageKey = global::Company.Module.Properties.Strings.strSaveInterestDetails8;
...
this.tabPage1.ImageKey = global::Company.Module.Properties.Strings.strSaveInterestDetails8;
this.tabPage1.ToolTipText = global::Company.Module.Properties.Strings.strSaveInterestDetails8;
So has anyone run into something similar or has better google-fu?

It is valid to have a string of zero characters, written just as '' , called the "empty string". The length of the empty string is 0. The len() function in Python is omnipresent - it's used to retrieve the length of every data type, with string just a first example.
In this solution, we use the len() to check if a list is empty, this function returns the length of the argument passed. And given the length of an empty list is 0 it can be used to check if a list is empty in Python.
Use len to Check if a String in Empty in Python # Using len() To Check if a String is Empty string = '' if len(string) == 0: print("Empty string!") else: print("Not empty string!") # Returns # Empty string!
This is a long standing bug in Visual Studio. Microsoft is aware of the issue, but still no fix. You can vote up the issue here:

I'm having the same problem, but with VS2008. However, a VS2010 Web Developer Express version is also installed on my system (since a couple of months). First, I was developing in a project that uses multiple language resources and then I opened up another VS solution to change something on a form. The Windows Form Designer replaced all the empty strings in the Designer.vb file with a string resource identifier from the first project!
I could solve the problem by closing Visual Studio and reopen the solution.
