  Could not load SSL library error
Posted by: bob9999 - 12-07-2018, 06:10 PM - Forum: IntraWeb General Discussion - Replies (3)

I just upgraded to IW15 ultimate in delphi 10.2.  Now when I am loading the local standalone gui, there is the message "Could not load SSL library" but my application loads in the assigned port 65100 and I seem to be able to run this locally OK.  When I install this with no GUI as a windows service on a server, it does not seem to listen to the port at all or something else is wrong since there is the message :TIWServiceThread.Execute: Could not load root certificate" is the log when I start the service.  On the server I cannot load the application at all.

I tried installing OpenSSL 64 bit since I kept seeing that all over the place on threads but the SSL messages persist.  On the Atozed SSL download page the package links there are crossed out and the links broken.

In the previous bundled IW14 version the port would be randomly assigned so I upgraded and locally the port is what I assign but on the server that same port seems to have an issue.

The key issue I am trying to solve on this thread is the SSL messages and the port information is just added for clarity on all that is going on at the server.

Cheers.

  IWFileUploader SSL Negotiation failed (solved - mea culpa)
Posted by: mschumann - 12-07-2018, 04:04 PM - Forum: IntraWeb General Discussion - Replies (1)

I have a webpage (itc-ms.de) written in IW15 (Current Version, Delphi 10.2 and 10.3) where I use a file-uploader to allow customers uploading data. This worked well while I was using the IW application directly in the internet.

As I have quite some apps and pages, I use an apache server that splits requests to the apps and pages and I only have to apply the certificates there.

In case of itc-ms.de apache talks to the IW application internally in plain http on port 888


Code:
ProxyPass / http://192.168.2.14:888/
ProxyPassReverse / http://192.168.2.14:888/

I now discovered that upload no longer works, it fails with error "IWFileUploader1: SSL-Aushandlung fehlgeschlagen (translated: SSL Negotiation failed).

I have disabled SSL in the IW application and do not understand, why this is broken now. For strangre reasons the same error occurs if I directly access http://192.168.2.14:888 internally but not if I debug the app locally. Browser is always current Chrome.

Any Help is very appreciated.

Mea culpa - it had a totally different reason: In ione event of Uploader I send an email and I accidently removed the open-ssl-libs. So the send email was the root cause.

  TreeView with Panel below nodes?
Posted by: cpstevenc - 12-05-2018, 04:02 PM - Forum: IntraWeb General Discussion - Replies (1)

Greetings!

I have a deal to where I want a tree view, but once I get to the final node in a branch, to show a panel below it.

Best example I have of something like this working currently out there

[Image: 55f2240720dc5522b219a61219731408.png]

[Image: d4b425acd45ffe030509122fd0cac7b6.png]

So could be at the end of more than one branch and see an interactive panel below them. 
Buttons, images, ect.

I was looking at the CGDEVTools JQuery Demos and I did not see anything showing a more advanced tree viewing experience
other than slightly enhanced typical tree viewing.

I have the TMS controls also, but theirs too doesn't seem to expand much on things other than checkbox/radio button support.

If you notice, even on a node level they have an input box level too.... 

Using Tokyo 10.2.3 and latest IW 14 currently.

Only thinking I have is this has to be just all custom HTML / JavaScript for now and figure out how to hook in callbacks and all that to make it play out properly?

  intraweb 14.2.5 and IE 11 and Firefox
Posted by: msgopala - 12-05-2018, 03:34 PM - Forum: IntraWeb General Discussion - Replies (3)

Seattle 10
Intraweb 14.2.5
FastReport 5

my application runs fine in Chrome but has problems in IE 11 and Firefox. Regions are cut off (ClipRegion property) and IE doesn't like the initialization of heights at form creation or at FormRender, repositioning is a problem too.

I have tried separating the code by browser type but main form always scrolls to the bottom of the screen in IE.

Please advise and point me in the right direction.


Thanks in advance

  Issue in TIdSSLIOHandlerSocketOpenSSL.OnStatusInfoEx
Posted by: Codehunter - 12-04-2018, 10:05 AM - Forum: Indy - Replies (11)

Hello!
I found an issue by accident in TIdSSLIOHandlerSocketOpenSSL.OnStatusInfoEx for the need of writing an NSS-file to decrypt TLS-1.2-communication with Wireshark. It seems that the declaration of SSL3_STATE in IdSSLOpenSSLHeaders.pas shifts the memory content from the DLL one byte to left. When i shift the S3-Pointer via Dec(PByte(S3)) also one byte to left so it will work fine.
Please have a look for this thread in the german Delphi Praxis forum for sample codes and screen captures from IDE debug.

  How to use JavaScript in IW
Posted by: ShaneStump - 11-30-2018, 03:54 AM - Forum: IntraWeb General Discussion - Replies (2)

Howdy All,

I am trying to call a javascript function on a control from a C++ async event.

If the region control's name is InformationPanel, and I wish to call a method called collapse with a parameter value of 'show' or 'hide', how do I execute a command of such from C++/Dephi code:

$(InformationPanel).collapse('show');

Also, how would I register a callback on a function of the format to call a Delphi event:

$('#InformationPanel').on('hidden.bs.collapse', function ()
{
 // do something…
})

I have tried the normal callback method/register like I have for button onclick events, but this one complains in the browser's console about a syntax error on my hooking of the event.

Thanks in advance,

Shane


Howdy All!

I knew I had called the function before. For those who don't know, the solution to call the aforementioned method is as follows:

WebApplication->CallBackResponse->AddJavaScriptToExecute(L"$('#INFORMATIONPANEL').collapse('show');");

I still cannot get the

Hi,
I am new to Intraweb components. Tried to build a toy app using TIWDBGrid and TIWDBNavigator, but found that the navigator was not driving the cursor on the grid. Where can I find help doc / demo for these two components?

  Delphi INDY + SSL + Socks
Posted by: evgenij-evgenij-89 - 11-29-2018, 09:42 AM - Forum: Indy - Replies (1)

There is a problem: When using a Socks4 proxy is not running https, the redirect goes to http. Libraries are, uses are connected.

Code:
var
 https: TIdHTTP;
 ssl: TIdSSLIOHandlerSocketOpenSSL;
 sock: TIdSocksInfo;
begin
 https:=TIdHTTP.Create(nil);
 ssl := TIdSSLIOHandlerSocketOpenSSL.Create(https);
 ssl.SSLOptions.CipherList := 'ALL';
 ssl.PassThrough := False;
 sock := TIdSocksInfo.Create;
 sock.authentication := sanoauthentication;
 sock.version := svSocks4;
 sock.host := '201.222.29.86';
 sock.port := 4145;
 ssl.transparentproxy := sock;
 https.IOHandler := ssl;
 https.HandleRedirects:=true;
 try
   https.get('https://www.facebook.com/');
 except

 end;
 FreeAndNil(sock);
 FreeAndNil(ssl);
 FreeAndNil(https);

If you remove the socks4, then all is well:

  Could not load root certificate
Posted by: JuergenS - 11-28-2018, 11:20 AM - Forum: IntraWeb General Discussion - Replies (5)

Hello,

I have a problem with loading my certificates with the indy server.

If i link my application with 64 bit static libraries i receive this exception message (EidOSSLLoadingCRootCertError) at startup:

Could not load root certificate.
error:00000000:lib(0):func(0):reason(0)

Working with 32/64 bit dynamic packages and 32 bit static libraries is OK.
Startup with HTTP.SYS is OK, but i can't open my website with my self signed certificate by any browser.

This are the linked libraries:

#ifdef USEPACKAGES
#pragma message "Link with packges"
#pragma link "IndyCore.bpi"
#pragma link "IndySystem.bpi"
#pragma link "IndyProtocols.bpi"
#pragma link "Intraweb_15_D10_2.bpi"
#elif _WIN64
#pragma message "Link with static libraries (64 Bit)"
#pragma link "IndyCore.a"
#pragma link "IndySystem.a"
#pragma link "IndyProtocols.a"
#pragma link "Intraweb_15_D10_2.a"
#elif _WIN32
#pragma message "Link with static libraries (32 Bit)"
#pragma link "IndyCore.lib"
#pragma link "IndySystem.lib"
#pragma link "IndyProtocols.lib"
#pragma link "Intraweb_15_D10_2.lib"
#endif

C++Builder 10.2.3
Intraweb 15.0.14

Do i need any other 64 bit libraries or anything else ?

Best regards
Juergen

When inspecting theServerController form properties, this property does exist.
