[How can I insert a paypal paynow button on uniguiapp]

Same problem.

 

i'm doing a new proyect that allow payments with paypal and credit cards.  

it's stay at initial state, but the main problem is do the payment ,capture the paypal response and integrate it width unigui application.

 

there are several ways to do this, like using an asp.net or php script that do capture the payment and store the result on a database.

Peharps best method is using a thirty party components like http://www.nsoftware.com/ibiz/paypal/technologies.aspx?sku=bld5-a to control the payment.

 

Some advice will be appreciated.

[Unigui call Datasnap function simultaneously]

In unigui applications, each user session can't share same vars/objects, becouse each user session have her own thread, then better way is create ojects/vars into unimainmodule.

 

Remove ClientModule1 from autocreate, declare public var on mainmodule class, and create it on mainmodule.oncreate

 

procedure TUniMainModule.UniGUIMainModuleCreate(Sender: TObject);
begin
 Client:=TClientModule1.Create(self);
end;

 

then, in mainform you must access UnimainModule.Client

 

Procedure TMainForm.UniBitBtn1Click(Sender: TObject);
var
 i,x: Integer;
begin
 UniListBox1.Clear;
 for I := 1 to 10 do begin
   x:= UniMainModule.Client.ServerMethods2Client.RetValue(i);
   UniListBox1.Items.Add(IntToStr(x));
 end;
end;

[Need DbEdit with a Button at Right]

Use a Tunipanel for Tuniedit and Tunibutton Parent.

[error 404]

404 it's a generic error that webservers send when file page not found.

 

using IIS you can personalize your own error page message.

 

But if your are not using IIS, you need know that unigui use a indy's http server modified version.

 

for doing this, simplest solution is modify the \UniGUI\uIndy\uIdCustomHTTPServer.pas, catch the error after FOnCommandGet event, and put your html code or load it from file.

 

it's not best elegant solution, but it works !

 

procedure TIdCustomHTTPServer.DoCommandGet(AContext: TIdContext;
 ARequestInfo: TIdHTTPRequestInfo; AResponseInfo: TIdHTTPResponseInfo);
begin
 if Assigned(FOnCommandGet) then begin
   FOnCommandGet(AContext, ARequestInfo, AResponseInfo);
   if AResponseInfo.ResponseNo=404 then
     AResponseInfo.ContentText:='PUT YOUR HTML CODE HERE';
 end;
end;

[UnifileUpload automatically]

Hi all.

 

If i call to unifileupload.execute, it open's a new Uniform dialog, then user need click a button to browse file and when selected, then click to another button to upload.

 

It's possible do this in one operation without intermediate uniform dialog?

 

example, calling unifileupload.run, user browse file, and then when user select browsed file, file will be uploaded automatically.

 

i'm trying to do this, accessing UniSession.FormsList.Last,and calling the buttons, but cant see the way.

 

UniFileUpload1.Execute;
F:=TUniForm(UniSession.FormsList.Last);
F.Hide;
//how to do that ?
//F.SelectButton.Click;
//F.UploadButton.Click;

 

 

thanks.

[How to send a form via post method to a external URL]

This can not be done with unigui. You need use Indy, or another http/sockets library

 

 

procedure TForm1.Button1Click(Sender: TObject);
var
 http: TIdHttp;
 params: TStrings;
 Response: string;
begin
 http := TIdHTTP.Create(Self);
 params := TStringList.Create;
 try
   params.Add('var1=value1');
   params.Add('var1=value2');
   Response := http.Post('http://dec.clubdelphi.com/temporales/pruebas-post.php', params);
   ShowMessage('Response: ' + Response);
 finally
   http.Free;
   params.Free;
 end;
end;

[Unimage Flicker problem]

It is related to way browser handle images. Some browsers clear the image place holder before loading a new one.

 

Instead of uniImage you can use TUniCanvas to render images. It should resolve flickering.

 

thaks Farshad , but using unicanvas, painting every 100ms, cpu goes 100% and it's too slow. i will try with some html/javascript or ussing an applet and load on uniurlframe.

 

thanks.

[run files from unigui?]

you can't not do it on client. client browser segurity dont allow it.

 

in spanish, sorry bad english.

 

no puedes ejecutar un archivo directamente en el navegador cliente, pero puedes generar un link html en un label y que el usuario se descargue y ejecute el programa. Busca en el foro porque esto ya se ha preguntado y respondido un monton de veces.

[Security issue]

I think that if you want more control segurity, create unigui as ISAPI, and use ISS.

 

 

i don't kwnow if it's possible, but if you need unigui app as service and you don't want use ISS, perhaps you can create a windows user, start service with this user, and grant file permissions to this user only for the files/folders that you allow to access.

[How to show the forms in sequence?]

I know there is a solution of Callback for Dialogs. But how to show the forms in sequence?

 

procedure TFrmClientFindPages.BtnClick(Sender: TObject);

begin

Form1.ShowModal;

Form2.ShowModal;

end;

 

 

Thanks for your answer!

 

Same method

 

define a funcion on TfrmClient that will be the callbacks like

 

Procedure TFrmClient.Callback1(ModalResult:Integer);
Begin
If ModalResult=MrOk then Form2.ShowModalCallback(callback2);
else Donothing;
End;

 

and pass it on a new function when call form1.

 

Form1.ShowModalCallback(Callback1);

 

then, when form1 onclose, call to callback.

 

see this

[Twebbrowser or TEmbeddedwb]

You can use another vcl componentes on unigui applications, but they not show on unigui client web interface, becouse then run on server, and not on web client. Only unigui components can show on web client interface.

 

For load an url on unigui app, use uniframeurl.

[unigui run external applications]

you must provide a link, in a label, then user must be click, and download & execute downloaded application.

 

   
Var s:string
Begin
 s := ServerModule.LocalCache + 'Myfile.exe';
 UniLabel12.Caption := '<a href="'+s+'" target=_blank>Download File</a>';
End;

 

another solution is creating an activex, embedded on an html, and load it on an uniurlframe, but this only work on iexplorer.

[Using ActiveX on server side]

i think that simple way is

 

- capture codebar image file on client side (don't know how you do that, and it can be the problem).

- upload captured file to the server using tunifileupload and store it on temp server folder.

- on uploadfile, server process the uploaded file image, using FineOCR (using com, activex,etc) , and show result to the client.

 

 

if you are using a usb/keyboard codebar scanner on client side, you only need capture keyboard keys and don't need process the image file with FineOCR.

what kind of device are you using to capture image codebar ?.

[Simple file browser]

Just do what you would do in a regular VCL app. Use findfirst, findnext, etc.. There are no shell components in uniGui.

 

Yes, but this only get server files (where unigui application is running).

and we want browse client files. .

[Block session]

redirect on terminate

and to terminate session

 

Unisession.UniApplication.Terminate

[Simple file browser]

do you want browse client files, or server files ?

 

i'm also interested in this, but i think client browse files it's not possible.

[FastReport on standalone server]
