I have made my VB application available to the entire US and it has been running without incident for several months, so I know there are no bugs in the basic code. Recently I have had a few people in India download the application and they have reported an error where the app parses the current...

I'm attempting to clean up some MVC code to make sure no memory leaks exist. I have a few processes where a Controller sends a data table or two to a View in ViewBag so the page can display the data records. At that point, I no longer have Controller access these data tables to dispose them...

My project is finally available online. It has been in the making for years and has been very educational. This post is just to say thank you to the selfless folks who have helped me through this forum to make it happen... Especially John H and JM Cilhinney. You two absolutely carry this site...

This may seem a little trivial, but I'm a nut for making an app work with the keyboard and avoid making the user reach for the mouse when ever possible. I have a Help page for my app that is shown on a web browser control. This is easy for me as I can update the help page quickly and easily...

In a DataGridView where the Selection Mode is set to Full Row Select, single row selection and the row's DefaultSelectionBack Color is set to a particular color, the user becomes accustomed to seeing this selected Row's backcolor when they click on a row. If they are clicking the row with the...

Many times I've read this advice: 'Do not call an event handler directly.' ... such as 'Button1_Click(Me, Nothing). I'm curious to know why this is generally a programming error. It seems to me like a way to reduce the number of lines of code. What's the down side ?

Is it possible to get the bounds / location of an item in a standard Combo-Box Drop down list?

As Visual Studio provides a default Dotfuscator for personal use, I checked with PreEmptive Dotfuscator about their pricing for the version used for commercial apps. The 1-Year term subscription price is $4,250. They also offer a 3-Year term single-payment option for $11,225. For this kind of...

I've been searching the internet for information about pre-compiling .NET code to native machine language. It seems that .NET Native is what I'm looking for but all of the info I've found online is several years old... Including Microsoft's at March of 2017 which states that "For Windows apps...

I've been going back & forth on the issue of user input validation as far as protecting my MVC site from xss attacks. I'm using VS2019 with .NET 4.8. The app includes a very simple feedback forum with user input for Name, EMail & Comments. From the controller, existing database data is sent as a...

I'm looking for some guidance with javascript. I was hoping JohnH or jmcilhiney might also post their expertise on some site that deals with javascript. They both have helped me so much in the past.

It seems no matter how long I do this stuff, I continually get hung up on the ridiculously small stuff. Here's the only code on a simple form that is supposed to set the width of a panel (Panel1) to be 30 pixels less than the width of the form and center it. (15 pix on each side of the...

'Need a little advice... I'm preparing an MVC web site that will accept user input such as Name, E-Mail, Date, Payment Amount and a unique User ID. From my site the user is redirected to PayPal to handle a secure transaction and return all variables back to my site. I began thinking I'd need...

This is some HTML & Javascript for changing an image based on the users' selection in a drop-down List Box. I would like to accomplish the same thing without using Javascript. This snippet is in a View within an MVC. Is there a way this can be done through HTML exclusively or maybe replace the...

I need some guidance: I have an app that will be available for download from the internet, initially as a trial version. If / when the user decides to purchase the app for use beyond the trial period, they would link to my website to fill in a brief form and the server should return a unique...

Something happened during my most recent build of a project that coincided with the time the latest VS2019 update came available. After the update, all debug stepping through the code was barely moving along. Where I used to click through the code as quickly as I could hit the mouse button, I...

I know I'll get chastised for my method here, but that is precisely why I come to this forum. I appreciate being corrected and I can't think of another way to do this ... One form initiates another small form that is a very small window on top of the main form and is used as a very transient...

'Getting close to deployment, in which I'd like to make an app available for sale online, I've started looking more closely at Microsoft's License terms for the VS Community edition. The license states: 1. INSTALLATION AND USE RIGHTS. a. Individual License. If you are an individual working on...

Here's something that caused me to lose hours of coding time while head scratching & fist pounding, and although I've found the culprit, I still don't know WHY it is an issue. After making a massive jump from VS2008 to VS2019 Community, I ran into this issue that didn't exist in previous...

Here's another beginner's question from someone who's been doing this long enough to know better... When we talk about disposing objects to free up used resources, is it possible that some undisposed resources could continue to take up memory after the program application has closed?
