I have a VB2005 winforms application that will loads city data from my database table. This is to ensure that the user enters the correct city spelling, in order to receive an accurate quote. Currently, there are about 150K cities that are being loaded to the dropdown listbox on page load. It takes about 30-40 seconds for that page to load.
My initial thought was to allow the user to select the state first. Then load the city values. But the user has the option of going back and requesting a quote for a different city / state.
Is there a more efficient way to handle this?
Quotes are based on state and city name? If so, your approach sounds good, but consider basing quotes on zip instead, or zip/city name. Not everyone will find their city in your 150K list, and some don't live in named cities at all.
For starters you could have a BackgroundWorker or Thread load the data in the background into an array or list. You'd then pass this data to the comboBox when needed.
If you use this method, you must find a way of reindexing the fields from time to time though.

I'm working on a screen flow. The idea is to have a lookup component the user can search a contact. Then I would like to display the information from the Contact (Account Name, Contact Name, Number Email) and I would like to be able to have the user update that information if needed. I just stomped on how it can be done. I know it should be able to be pulled from the record ID in some type of way and maybe use an Assignment to display the information. Can someone guide me on a next step or if anyone has an instructional video would be helpful.
Thanks
You wouldn't be able to display the looked up contact's fields on that screen as soon as you populate that field. That would be something only possible in code (aura component or lwc).
What you can do, however is -
Get Record element after that screen element. (Get Contact, where Id = lookupcomponent.recordId)
Then EITHER:
use the new Fields (BETA) option on another screen Fields (BETA)
(this method is easier, doesn't have as much control and is limited on fields, depending on data type, you can use)
add inputs one by one and set the default values Add Fields One By One
(this method allows more control)
Then, you will need an update element. If you used the Fields (BETA) you can just update the record variable. If you did the inputs one by one, you will need to update the contact and set fields individually.

I am taking a database design class and for a project want to make a database of my mom's digital photos for her. I haven't dealt in application up to this point, only theory, but I have Access. Therefore, ideal answers don't suggest non-database solutions and don't assume I know much about actual database implementation. Solutions specific to Access could also be a plus. I hope that precursor saves some time and effort.
Theoretically, my mom wants to see all photos of pets from '05-'07 in raw format, and she enters an appropriate query. I suspect I can handle it up to there. However, at the moment, the best I can figure out to do is to return a column of either attachments or OLE objects. 5 clicks per photo is not ideal. I need a faster way to present the images. Opening them all in a grid of thumbnails or as a one-click-slide-show would seem the natural fit, but whatever works. How can I accomplish this?
Less important but worth consideration is the fact that, at some point, it would be great if this same type of system could be implemented on the internet for all of the family reunion photos she has taken, but I will take what I can get.
Use one form to get parameters for the query. then use another form(more processing) or report(if printing) to show the selected pictures. I will not cover passing parameters but here are some links.

https://learn.microsoft.com/en-us/office/vba/access/concepts/forms-design/apply-a-filter-when-opening-a-form-or-report
There is a complication, in Access pictures are usually stored in the attachment type. the attachment column can hold many pictures in each record. So if we have a table called Pictures with an attachment type column also called Pictures, then each individual picture is actually stored under Pictures.Pictures.FileData.
So to display the picture query we use a form/report with default view set to Continuous Forms (displays many records or in this case pictures on the same page) then in the details section of our Display form we place an attachment control and bind that control to our filtered Pictures.FileData.
Format and add functionality to taste.
I am outputting form inputs on the final page of a checkout field, titled "Review & checkout"... on this page I display the plan the customer picked and the personal info they provided so far.
I have no problem showing fields like Name or Email, as the value inputted is being shown, as Angular displays whatever was in the value="" field of the input.
To display the subscription plan that the customer picked, it's trickier.
The value field is already being utilized to tell stripe which plan the customer should be charged for.
How can I get around this problem?
I am able to display the stripe-id for the plan but it is not user-friendly. They are id's like trad-2-5, trad-2-6, trad-2-7... so what I want to do is display a custom title when trad-2-5 is selected, and so on...
Any help is greatly appreciated!!Thanks
There are a couple of ways you could do this.
The really silly answer is that you can just create a map of plan ids to human-readable descriptions in the Angular controller code, then display that. This might be enough for what you want, but it's also pretty hacky, and not a lot of fun to maintain.
The less silly answer depends on where these plan ids are coming from. If they are coming from an endpoint on your server, which gets them from Stripe's plans endpoint, then you could also pass along the display name of the plan from that endpoint. If the plan id's are hard coded somewhere, or whitelisted, then this may not make sense. However, that display name is what will appear on the customer's invoice, and credit card statement, so it'd be nice to make it match up with what they see on the checkout page.
I am trying to create a incident log in safesfore. The key aspect is that everything can be added on the same page reducing the amount of clicks that have to be made. There are 6 fields i have created:
Date Opened, Date closed, incident, reported to, reported by and notes.
I was wondering if there is a way to create an "add new" button that will create another row of the fields i have just lised. The idea being that the page does not refresh it is all done in real time.
Many thanks
You'll need a custom Visualforce page implementation.
There are 2 ways to do it
1) Building a list of records on apex and iterate over that list displaying the fields on the front end (vf page apex:repeat)-- Then when the button "add new" is clicked you'll append an empty record to the list and re-render the apex:repeat to reflect the changes.
This is good because you don't need a lot of boilerplate code since the records with be binded with the backend. However, the rerendering can lead to some performance issues in my experience.
2) Build a custom Javascript implementation, where you have an in memory collection and using DOM manipulation add/remove rows of the list. When the user saves the data from memory must be sent using JSON and a VF Remoting method can perform the JSON parsing and saving the rows.
Both are valid, the first is good to avoid boilerplate but the second is much faster (but you need to write some boilerplate).
Here is the link to where the data can be found. Scrolling down to Surface Data : Daily and selecting the Global and U. S. Web Page Icon. On the next page, Select the radio button Country and press continue. From the next page's drop down menu, select any state and then press the radio button for entire state (I need more than 100 stations per day).
The next page allows you to select the date range.
I am dumping these data files into excel and sorting (which is a pain, since it could obviously be
automated).
Is there a way I can access the most current data via a script (VBA or otherwise)?
My main problem is that I can't send the server a simple request to obtain the data. Also, there is an FTP site but only allows .gz files to be downloaded, each over a gig, so its not reasonable for my situation.
Any help would be appreciated!
There National Climatic Data Center has several data APIs available for this.
