    Multiple databases or one big database?

    in General

    Posted

    I developed many DB projects. Some for 10.000 users. Safety is of course base problem. But there are diffrents ways to increase safety, separating BD's is not:

    1. DB replication online

    2. Hot backups

    3. DB access protection

    I work with PostgreSQL, that is quite advanced DB, like Oracle etc. What DB engine are'u using ?

    Hi.

     

    I strongly recomend to use one DB. Why:

    - many structures of data are common for all customers, it's no use to replicate it. One job for many future customers. Every common structure with "customer_id" field, and index for this, no efficiency problem

    - future changes for structures - one change vs many the same changes for all customers

    - new customer = new customer_id, it's no use to create next db

    - one DB = easy backup

    Hi,

     

    My WebMode project contains UniImage and UniTimer. Every 1 second new JPG image (few KB) is loaded and displayed in UniImage. Work's fine, but while changing pictures they flicker. How to avoid it ?

    Hi,

     

    How to set font attributes for whole row instead of particular cells ?

    OnDrawColumnCell event allows check value of field in current drawing column. Is possible to get value from another column of the same row ?

    Buttons + Transparency

    in General

    Posted

    Hello everybody:

     

    I just start work with uniGUI in this week. I read it before, but I did not use it, so may be in the near future my questions will be caused by lack of knowledge.

     

    I created a simple project in which I put a button (TUniSpeedButton) with a picture. The image is in BMP format because the Glyph property of the button will not let me use another, yet when the generation for WEB PNG format is generated. In the Windows Application it looks good with transparency, but on the WEB page the background is drawn with the color that supposed to be transparent. My questions are:

     

    1- There is a way to do that, i. e. to obtain transparency for the WEB???

     

    2- Will be possible to use the same color (Pixel Color at (1,1)) for Transparency in the PNG Generation?

     

    3- Will be possible to add property "Transparent Color" for Transparency in the PNG Generation?

     

    4- I noticed that the name of the images created for the buttons always use the same name and are created in the first request to the application and then used in all the remaining requests. Will be possible to use the same name of the button, and put a property in the Main Server Module to specify that do no delete the images??? In this case I can make PNG images by myself with the adecuate transparency.

     

    Best regards, Dionel Acosta

     

     

    Hi,

     

    Set Pixel Color at (1,1) = clFuchsia, that works for Web Mode as transparent color.
