IntraWeb 15.5.8 TIWRegion Showing as white even when set to other color. This issue only effecting design as the color does take effect for actual application but the designer always showing the background as white. I just upgrade from 1.5.3.1 to 15.5.8 and ran into this issue. This issue even applies with creating a new project and placing IWRegion on the form and changing color.

I try this in Delphi 11.3 but also test it in Delphi EX2 and the same thing.

I've a Delphi 12 VCL app that I'm using Intraweb and sgcWebsockets to develop a web page based remote control for. Use a browser to control the app as you would as if you were at the computer sort of thing. To make the web pages nice for iPhones and such, it requires 2 pages. I put a websocket server in the VCL app and a client on the first page of the Intraweb app. Works great. Buttons work, data flows back and forth. The problem comes when the web app is switched to the second page. The client on the first page disconnects. Adding a second client to the second page doesn't connect either. Tried adding a second server with diffferent port numbers on the VCL without success. I'm using the two page design outlined in the Intraweb 15 example "MultiPageAPP". How can I get both pages to 'talk'?

Hi All, 

After updating Indy I am getting this error. 
[dcc32 Fatal Error] Unit1.pas(9): F2051 Unit IPPeerCommon was compiled with a different version of IdIOHandlerStack.TIdIOHandlerStack.CheckForDisconnect.

Any clues on how to fix this?

Thanks!

I'm using Templates, the page is responsive, but I have a control that is not. So, I have placed it on a Region, and so my region is now responsive and I was hoping to either have that control auto-resize with AlignClient, which it does not, or set that control's width to Region's width in some event - but now for the life of me, I cannot find any event that is triggered around that time that I can use.

Form events do not matter with Templates. Region's OnRender still has the original design sizes, so it's of no use. OnAlignPosition is never triggered.

Has anyone done that before?

We have a nice app in IW15 with Boostrap 4.6.2 running.
Now we are asked, for security reasons, to upgrade to the latest Bootstrap version (currently 5.5.3).
I cannot discuss if this makes sense, its a public institution, its in thier standards.

Is there any support for Bootstrap5 planned, in sight? Does anybody know if BS5 is compatible? Can I just replace the JS-files and continue with the BS4 Delphi components?

Any help appreciated.

The provided example is very simplistic: you give the chart 10 values and 10 / matching number of  labels and that's it.

What do I do if I have a very long list of frequent readings for a small number of hours or days? - how can I stuff all these values into the chart and only have 24 hour labels? Or 7 days worth of labels? And possibly decimate it as well? My "X" values for the data points is in Unix time format - seconds from something in the past, or I can make it TDateTime instead, but I would want the few shown labels to refer to around the current time / date.

Also, if I have gaps in this data, I want it shown as a broken line - - - - - or something. Hopefully automatically, without actually looking for any gaps in the Delphi code.

It looks like ChartJS supports both, but I could not figure out how to feed this into the TIWChartJS component, hope you can help...

Hi,

I need a control that the user can enter 20 digits into in 4 blocks of 5 separated by hyphens (ie 00000-00000-00000-00000)

Is it possible to use the DataTypeOptions.Pattern property to achieve this? If not are there any other suggestions?

Thanks,
Tim

Delphi 12

Resource IW_DT_DBNAV_FIRST not found.

The IDE adds it and can be modified but the message continues to pop up.

15.5.8

not sure if it happened in earlier releases.

Any ideas?
TIA

Hi guys,

there is a new update with some important fixes + more performance improvement and a few other things (like the MSHeapMM memory manager, ready to be plugged in)

Enjoy! 

After some more time playing with Delphi 12 and supporting different applications

1) Indexes in lists are now NativeInt. It means that in 32 bits, nothing changes, but in 64 bits it becomes a Int64.

Whatever TList, TStringList, TObjectList, etc. descendants that you have in your code where you have new Get() and Put() methods for the list you will need to rewrite and (the worst part) probably declare a new alias for the NativeInt type if you need to code to keep compatibility with older Delphi versions.
Warning: The compiler doesn't give you clear messages for this case.

I have really no idea why Embarcadero decided to do that, really. I asked Marco Cantu on his blog but seems that he didn't like/approve my question. Funny. 

2) OnCreate/OnDestroy events of Forms are triggered from AfterContruction/BeforeDestruction methods, not from Create/Destroy as before. It means that code where you override the contructor of the form and then initializes data inside OnCreate may start failing. Check this example:
