I have declared a variable as public (Visual Basic 2008). As a result I can call its value in all subroutines. However I cannot change its value in any of the subroutines?! How to do that? The variable I'm having trouble with (see code below) is called 'antwoordbestand' and I want to change its value in subroutine startKnop_Click.

VWD 2008 Express. Windows 7 (64 bit). I want all my work and settings for VWD 2008 to be stored in the public (shared) documents folder. There are settings under Tools>Options to specify where projects and templates are stored, that is part of the answer. However, whenever I open VWD it always creates a "Visual Studio 2008" folder in my personal Documents folder where it apparently stores some settings. How can I make VWD work entirely in the "Visual Studio 2008" public folder for everything and NOT create the personal folder?

View 9 RepliesI have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

I have a JavaScript wrapper that I initialize on body load and set to a global variable.
Just after creating the object, I have full intellisense, but when referring to it later, from another function, the intellisense is lost. I presume this is because of dynamic typing:
var myWrapper;
function onload() {
myWrapper = new Wrapper(args);
myWrapper. //intellisense here.
}
function whatever() {
myWrapper. //intellisense lost.
}
I get round this by pretending to create the object again before my code, and then deleting the line:
function whatever() {
myWrapper = new Wrapper(); //pretend to create object again.
myWrapper. //intellisense returns!
}
Has the inference been improved in vs 2010, or is there any way to tell Javascript about the type of object I'm currently working on?

I have a publice variable to be used in the same webpage. when the user click on button 1, it does some process and assign a value to my public variable. After that, the user can click on button 2 which needs the public variable value to function. However I see the value of the public variable is 0 when I click on button 2.

I'd like to know how to declare a variable in my code behind page that I can use in all the subs of my code behind.
I tried in after the Partial Class declaration to declare a "Public String" :

and to use it in my subs but when I use it from a sub to another I loose the value affected in another sub.
Is there a way to use a Public variable from a sub to another (I'm actually using a session variable in order to do it and I'm not sure it is the best way)

View 4 RepliesFor my Dynamic Data site I have a table that has a join to a number of other tables. If I use the standard page for this table I get all of my columns from the primary table and related tables (which is good) and the appropriate literal values from the related table (which is great). The bad part is the order of the columns.
To address the order of the columns I created Custom Folder/Page for the table. I also have a partial class that controls date formatting. This takes care of the ordering of columns fine (which is a step forwared), but now I'm seeing the foreign key IDs instead of the literal values from related tables (which is a step backward).
All I did was copy the standard page to the Custom folder for the table, turn off AutoGenerateColumns, and specify the column order and display name. Why would the foreign key change occur? As a side note, if addressing column order in the partial class is the preferred method I could go that route, but I haven't been able to understand how to do that in VB (I've seen many examples in C#, but that's not my strong point).
