C# - Using Codesnippet Until Condition Is True?

Nov 1, 2009

I've got this function which converts wav files to mp3. I call this from my button_click handle. The thing is, when the conversion is started, the rest of the code in the button_click handler continue, while the conversion is happening in a different thread. Now, I need the rest of the code in the button_click handle so continue to try until a boolean is true, so that I know that the conversion is done before the rest of the code continues. I've tried using Do While but it didn't seem to do the trick. Perhaps it's just me though..

How To Make A Statement Run If All Conditions Are True From Multiple Condition Or If Statements

Mar 22, 2011

I have a form that contains multiple conditional or if statements on several defferent for controls.

Example: Radio Buttons, TextBoxes and CheckBoxes.

I am intending to create an order form(demo) where the user can select multiple products.

I have a default order number that changes by one everytime an order is successful.

An order is only successful if all the information on the form is entered correctly.

My question is where do I insert the code for the order number?

Basically for the order number I have a counter that count by increment of one if an order is successful.

Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.

Where do I add the condition for the order number since all the fields must first be completed.

Do I have to create a whole line of if else statements?

If - Else Condition First Code Won't Execute - Add Some Codes Besides Readonly Being Set To True And False

Feb 10, 2011

I have a form called LogIn.vb which has no errors. After log-in, it opens the MainForm.vb which IsMDIContainer property is set to true. From the MainMenu, it opens a child form called Assure_Benefits.vb So far no problem up to this point. When Assure_Benefits.vb loads, it displays 2 DataGridViews with datasourses from my 2 tables in my database.

There is still no problem with the loading. Now, to show the difference between different user types, I only allow the admin to edit the DataGrid. SO I set the readonly property to true when UserType = "user".

I have no problem doing that. My problem is I want to add some codes besides the readonly being set to true and false but other codes are not executed and the program does not display any errors at all. i tried to add messageboxes on the if and else conditions to try if added codes will work but even the messagebox does not appear though the codes next to it are properly executed.

When my Assure_Benefits.vb loads I call for the subroutine below.

Private Sub SetControlProperties()
If LogIn.UserType = "admin" Then
MessageBox.Show("Yes") 'This line is not executed

[CODE]...

I can't seem to understand why the first code is not executed when the next codes works fine.

Multiple CodeSnippet In A XML .snippet File?

Jul 28, 2009

I'm attempting to supplement the help features for my code by providing other developers with code snippets. These produce skeletons of code which demonstrate how to use/call my classes or methods.

I've created a .snippet file and have placed it in the "%Visual Studio Folder%Code SnippetsVisual BasicMy Snippets" folder. I've used the Code Snippets Manager and ensured that it included this folder so that I can access the snippets.

Everything works well when I have 1 CodeSnippet tag within the root CodeSnippets tag....When I add more than one CodeSnippet tag to the file (each with their own title, and their own code example) I'm experiencing something strange.

The first CodeSnippet I've added contains code for adding something to my system, the second contains code for editing something in my system, and the third deleting something from the system.When I use the code snippet by right clicking and selecting "Insert Code Snippet", only the first code snippet in the file shows up as an option. When I select it, the code in the first CodeSnippet is inserted....but so is the code within the other CodeSnippet tags.

Do you have to have a separate XML .snippet file for each code snippet you want to make available?After reading through MSDN about creating Code Snippets I was under the impression that this could all be done within one file.

SQL Group By With A Condition?

Aug 16, 2011

Scenario: I need to create a report for the auditors for an ASP.Net application. I have a program that parses the XML of the web.config files in a directory for the authorization tag and creates a report providing which users have access to which folder in the site structure. The report is shown below.

UserName, Firstname, LastName, Directory, Roles, Access,
LastLoginDate

Problem: As you can see from the report some directories (the middle column with GISMO in it) show up twice, with both allow and deny for a user. I am wondering if there is a way to group the results in such a way that if there is a row that has allow for a directory then the deny's are not shown but otherwise they are.

Alternatively if this can be manipulated in VB.net/C# that is also an option. It comes back there and is pumped into an Excel spreadsheet.Edit: I should have explained better. I still need the deny rows to show if the user isn't allowed in the directory. But if they are allowed then there is no point showing the deny rows.

.net - If Then Statement Condition Being Ignored With Optimizations On?

Jun 16, 2010

I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees.BOTH side of this if then else statement are being executed?

Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation...

The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change?
