I have a very strange problem. I load my app, switch to the correct tab and then press the button I need to press. This runs a function and when I first load the page it may only provide part of the correct result. However if I wait a few seconds it produces the correct result in full. Any ideas why this might be happening?
Additional Information
The button simply checks through a list of objects returned via ScriptDB. Objects that are valid are displayed and objects that are in-valid are not. If the object appears again in updates the text to display how many have been found in the list (eg: the label would change from "Object A" to "Object A (2)").
It seems to me like it doesn't have the rest of the list somehow as it doesn't always stop at the same object. It's Very strange and not something I've experienced before. The other features of my app using ScriptDB work completely regardless of how quickly I use them.
I've figured it out now. I somehow had some erroneous data in the database which was returning a null field. I can only assume that this was from a import that I did last week from a spreadsheet.
This was copied from my comment to show that it has been resolved.

Sorry - I'm a total newbie with InstallShield. I've inherited an InstallShield 2013 project that presents the user with a dialog that let's the user select a SQL Server and based on their selection sets a value in a config file. That's not working, so I opened the project in IS and looked in the Text File Changes under System Configuration and there's nothing there that would do this. So how do I figure out where this is happening (or not happening in my case), and then how do I get it to work? I need to set both data source and initial catalog in a file called server.config.
So how do I determine what the user selected and then save that in this file? It looks like I can set up a Text File Change, but how do I access the values selected by the user? And how can I figure out where the "code" is that is supposed to be doing this?
Thanks,
Ben
I would try to track this from the dialog and controls in question, or by following the value through a verbose log. Since you say it doesn't work today, there will probably be an interruption in the flow I describe below, and since you don't know the full state of the installation project, it may be hard to identify. So search from what you know.
Top down: what gets configured
First, find the dialog that you fill out as a user making the selection. Then figure out the property that the particular control is associated with. Now you've got a thread; pull on it.
Search in the direct editor for references to the property. If the property is named MYCONFIG search for just that: MYCONFIG. You'll probably find some sort of use that looks like [MYCONFIG] instead, which is typically a format string specifying to use the value of MYCONFIG. You may also have to search all the files related to your project, as Custom Action implementations can be code stored outside of your InstallShield project.
The use may be in a ControlEvent, CustomAction, or some other table. If it's in a ControlEvent, it may be used to set another property. Ditto if it's in a CustomAction that sets properties (type 51) which may be easier to understand in the Custom Actions and Sequences view. In that case, also search for the property that gets set.
If you find it in a table like ISSearchReplace* or ISXml*, or IniFile, it's probably part of the Text Files Changes, XML File Changes, or INI File Changes, and that view should make it easier to understand.
Maybe that thread dead-ends somewhere. A property gets set, but never referenced. So try to search from the other end.
Bottom up: what gets written
If there are text file changes, xml file changes, ini file changes, or custom actions that reference the file you need updated, see where they get their information. Try to follow it back. If they're well written, you should be able to identify the property (noting that one called CustomActionData comes from a property matching the name of the custom action it's used in), and then trace that further back using the same ideas as above, but in the other direction.
Where's the problem?
If the threads don't connect, that's probably the problem. It's also possible that a custom action lacks permissions but doesn't reports a failure, or that the file name or path got misconfigured somewhere along the way. Look for small things like that if things look like they should work but don't.
It turns out that I misunderstood the problem and the project was never set up to change that value, so all I had to do was set up a Text File Change and it works perfectly. Thanks #Michael Urman for the thorough response - I really appreciate it!
this is one heck of a confusing question to ask so here it goes. Firstly, I'm not asking you to write me any code I just need help going in the right direction for what I'm trying to achieve here. Basically the task is this, I want to scan a select area of a web page's source code for changes and if something does change, I want to report it somewhere (like a console or something). However, I do not want just a notification of change, I also want what the change is/was. I've been looking into things like jsoup but I am still struggling to even find out what this is called.
Any pointers would be insanely appreciated. Thanks, Optimistic.
Here are some steps assuming this is from a node.js project:
Get the URL for the specific script file you're looking for a change in.
Using the request() module, fetch that URL.
Break the data up into lines (probably using .split()).
Find the specific line you are looking for either by counting line numbers of by searching for some representative text in that line.
Using some sort of search in that line (perhaps a regex), find the current value of the exact item in that line you are looking for.
Save the current value.
Then, at some future time, repeat this whole process and compare what you find to the previous value.
If this is being done from a browser instead of node.js, then use an Ajax call to retrieve the file. If the file is on another domain from your web page and that domain does not permit cross-origin requests, then you cannot solve this problem in an automated fashion from a browser in your own web page.
Here is how I would do it with Jsoup:
Document doc = Jsoup.connect(url).get();
String scriptCssQuery = "script"; // Tune this CSS query to find THE script you need.
Element script = doc.select(scriptCssQuery).first();
if (script != null) {
String scriptLines = script.html();
// Store the changing line somewhere and compare it to its previous value...
}
I am developing one application, in that I have 3 pages. In first page I have List Box with some data and in 3rd page I have application bar for navigating to first page. I will get the list box data from the server. Whenever I am binding the List Box with server data, it is rendering properly but if the user navigate from 3rd page to 1st page using application bar then List box is not updating with fresh data, it is still displaying old data. If user comes to first page using back key press then new data is rendering.
I am using observable collection to bind List Box data and used NavigationService.Naviagte() for navigation.
Help me to resolve this issue.
Thanks in advance.
I am not very sure about your problem because you haven't cleared the whole context. But assuming that your data is refreshing on back key press, I can suggest you use NavigationService.GoBack() instead of NavigationService.Naviagte(). The former method call is equivalent to back key press. NavigationService.Naviagte() creates another instance of the page in the memory while NavigationService.GoBack() takes you back to the previous instance. Hope this helps.
As I understand everything is fine when you start. But the update is not happening upon second return, i.e. Through navigation.
My thought is that all your code to do this is in the constructor, and since the page is not removed from memory the constructor will not be called.
Two solutions move the code to a loaded event. Simply in the constructor write this.loaded += eventname;
Or you could put code in the onnavigatedto event. Write as a new function protected override onnavigatedto.
Putting it in the navigatedto, would probably make your app less responsive if you do server calls. If you have the code in the loaded event then the information will be uploaded when it is done. Which means the user will have a moment with old information. You could then introduce a waiting screen if it is an issue.
I have a form with text inputs, check boxes, radio buttons, selects and an AsyncFileUpload control.
All of the selects are dynamically populated from the code behind, and one of them has a Select One added (which is removed when another option is selected) from my page controller object.
I have verified that none of the page's javascript is running in conjunction with the upload control other than the script that directly controls the client functionality of the uploader.
If I do not touch any of the other fields and attempt to upload a file I get an Unknown Server Error.
If I change away from the Select One option (which, again, makes the option be removed), I can now upload an image. My solution is to add the option in code behind and remove it once an option is selected from the client, but my question is this:
Why do I get this error? What is the reason for it?
I found the reason. My Select was an asp:DropDownList, and my code was expecting the returned data to be validated. Since I had changed the value from javascript it was no longer the same as what the server had sent, causing the exception I was seeing. The solution is to do those changes from the server instead of on the client. Simple solution to a perplexing issue.
Got a weird problem. I was debugging some code for a form and everything was working as intended for the most part when suddenly I began to get a "Method or Data Member Not Found" for every event of my form. It's like my form suddenly does not recognize any of my controls or events. I have all of my methods properly closed and did not rename any controls.
Any ideas on what would be the root of "Method or Data Member Not Found" for every single control with an event?
Thanks
Importing into a fresh database as talbright suggested gave me more descriptive error messages.
A fresh import, compact&repair, and renaming of appropriate control fixed the problem from occuring. As Remou suggested, regular maintenance can help prevent these sorts of problems.
edit for future readers: This problem occurred while using a shared front end file. So don't do that if possible.
I've found that any MISSING: reference can make the simplest of code fail.
Check in the visual basic window
Menu Tools -> References
look down the checked refences to see if any are MISSING
I just fixed the same error by renaming text and combo boxes something not so close to a concatenated Table & Field string. Actually just prepended those names with "tbx" and "cbx".
