Strategy For Converting A VB6 App To .NET?

Apr 27, 2010

Would it be a good idea to start converting forms into .NET one at a time which you would then invoke from the VB6 app via COM-interop.This way, by the end of the process you would just convert the 'shell' of the VB6 application into a new .NET app, and all your forms are ready to go in .NET.

Best Strategy To Simulate A .net Web Service Without A Server?

Apr 18, 2011

I have inherited a .NET 4 VS2010 solution consisting of a WinForms app and a web service. I don't have access to a server that's running a copy of the web service but I have to run, debug, upgrade and test the project that accesses the web service as well as the web service code.Later, I also want to quickly switch between a deployed web service and the code in my local projectWhat's the best strategy for changing the projects so I can make changes to both projects, test locally, deploy the web service then test against that? If I find issues, I want to switch back to "local" mode to debug.

Strategy For Events To Trigger Condtionals

Dec 24, 2010

I developed app which accepts user responses. I created secondary labels which I envisioned as larger "tool tips" which prompt the user. ("prompts")As the user inputs to either combo box or text box, the label should go invisible and a "prompt" for the next input should go visible.I am trying to use Selected Index Changed,Leave, or LostFocus events to accomplish the visible invisible change.Is that the most effficient way to accomplish my functionality? A twist I would like to incorporate: the purpose of the "prompts" is to guide an unsophisticated user through the app the first couple times.After familiarity is acheived the "prompts" can be annoying.My strategy is to allow user to turn off the "prompts" by a check box.Then my conditionals will test the checkbox. checked property and either show the "prompts" or not based on the test.

Sql - Branching Strategy For Release Based Db Project?

Dec 23, 2011

We have a asp.Net vb.net 2008 project on tfs2010. The project has one main branch and for any release we create a new feature branch which is finally deployed. Post production deployment we merge back the branch back into main branch.We are now also adding a db project to manage our SQL too. Question is how to version control the differential scripts. The db project contains all create scripts which is fine if we had to deploy thep project from scratch but the project is already live. So now any new release or hotfix would normally contain alter or change script practically.

Strategy For Developing A Multi Function Asp.net Web Application?

Mar 4, 2010

I'm about to start a new project and want some advice on how to implement.I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out.

If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules.to make things more difficult, there is some shared functionality like common users, roles and security.Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional.Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame.I can see that say, if I wanted to update the time management module,

TreeView Binding Strategy; TreeNode Casting?

Jun 15, 2010

I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property.
This would allow me to write some code like this:

Dim oBinding as Binding
Dim bs as New BindingSource
bs.DataSource = myObj

Strategy To Override Enabled Property Of A User Control?

Aug 5, 2009

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?

I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

Office Automation :: Strategy For Comparing Two Excel Ranges And Deleting Duplicates?

Aug 17, 2011

I have to compare two columns in two different Excel sheets and delete the duplicates. I have come up with several strategies that work, but I am searching for the most efficient way to do this. At first, I was sorting the columns and looping through them in the manner of a sequential update and deleting when the cell values were equal. But I discovered here an article by Mike Rosenblum that explained that it is much more efficient to stick the columns into an array and iterate them from there. So I was able to do that. There was a complication in that once I had deleted a row, then the array and the spreadsheet were out of sync. So I had to compensate by incrementing a variable each time a row was deleted, and subtracting this variable from the array index to calculate the row to be deleted in the spreadsheet.

So now I am wondering whether there is a better strategy. I thought that if I could merely hide the rows to be deleted and then find a way to delete all hidden rows at once after the loop was over, then this would eliminate the problem of the array and the spreadsheet getting out of sync and would make the code easier to understand. I thought of putting the row numbers of the duplicates into another array and deleting the rows after the comparing loop. But this creates the same problem of having to compensate the row numbers in the array.

Converting From VB6 To .net?

Jan 19, 2011

It is a program on which logic programs can be developed, compiled and downloaded into Programmable Logic Controllers. It is fairly big and complicated and the resulting .exe file is about 2Mb. I need to develop the program further now, and would like to use VB.net. When I try loading the VB6 code into VB.net, it changes all the variables of type Integer and String into type Object. It then states all through the resulting code that the default values are not defined. I assume that if defined as Integer and String variables do not need a default value, it would assume them to be 0 and empty. Any ideas why the program changes the variable types during the converstion? All forms start with 'Option Explicit', so all variables are defined.
