Crack Windev 17 32 Et 64 Bits
Dallas Whitmoyer
On the browser I was encrypting some data and sending it to the server. Think of it as double batch of SSL ? If hackers were able to get the private key for the SSL certificate they could decrypt the data between the browser and the server, however if that data is also encrypted with yet a different key, one that we randomly generate for each session, then all they get is yet more encrypted data.
The issue was that the CryptoJS function was returning an initialization vector to me as part of the encryption, however there is no way to pass that to the DecryptStandard function in WL. Therefore the first 128 bits of data was always corrupted. For example:
Saludos Marco, para windev, basta con incluir la dll en la carpeta donde se encuentra el ejecutable, por ejemplo Exe y de esa forma ya funcionar tu aplicacion. y para el lado de webdev en el servidor tengo la dll en la instalacion de webdev. Saludos!
Gracias Saul por responder, las dlls que proporcionas aqu fueron de gran utilidad y para mi caso del lado del servidor y de forma local fueron colocadas en C:\Windows\System32. (Lo comento por si a alguien le es de utilidad, saludos.)
Une version 32 bits peut cependant tre installe en cas de besoin, grce une ligne de commande de l'installateur INSTALL.EXE. Cette ligne de commande permet d'obtenir le choix lors de l'installation, entre la version 32 et la version 64 bits (du moment que la station a un systme 64 bits) :

Bonjour, Je souhaiterais savoir, comment savoir quel version de windev est install sur mon poste de travail. Si on install windev 32 bits par dessus une installation existante 64 bits que ce passe t-il dans se cas? Merci de votre aide. Cordialement Amine

Bonjour, lorsque l'diteur est lanc, son titre contient droite un rond avec 23 ou 64. Sans lancer l'diteur, il est possible de distinguer le mode de compilation d'une version installe avec le nom des excutables WINDEV*.EXE. S'il y a un fichier \Programmes\WINDEV64.EXE, c'est un version 64 bits. S'il y a un fichier \Programmes\WINDEV.EXE, c'est une version 32 bits. Il est possible d'installer sur un mme poste une version 32 bits, et dans un autre dossier une version 64 bits. Il sera ainsi possible d'utiliser la version 64 bits ou la version 32 bits (mais pas les deux en mme temps). Bons dveloppements !
I'm setting up a new database and am wondering if I should use bit, tinyint or char for a field that will indicate if a building has a basement. It would need to store 0,1,Null (Null if they are unsure if it has a basement). In C#, it would be nice to be able to have the IF statement look something like "IF BASEMENT" instead of "IF BASEMENT = Y".
I would use a bit, because it maps nicer over to a boolean value than any other value. For a radiobutton, I would think the same because you base it off of the checked boolean property. If you are taking radiobuttonlist, then the selectedvalue is of type char, but using bit only requires a simple ctype().
Bits can be in an index but they generally shouldn't be. The reason bit shouldn't be in an index is you only have 2 values (3 including null). For an index to be effective, the range of values should be larger than that and there should be a good deal of diversity in the values. According to the Microsoft SQL Server 2000 Performance Tuning Guide, the general rule is if a query accesses more than 20% of the rows for a given table, it's better to do a table scan than use an index. Given with equal distribution you're looking at 33.3% per value (I'm including the null... otherwise we're looking at 50%), that'd be a table scan. Hence the reason bits don't generally get put in indexes. It's possible, just typically not very useful.
As for space, SQL Server will automatically allocate 1 byte for the first bit. It'll fill in the rest of the byte with other bit columns as needed, up to 8. Then it'll start on the next byte if there are more bit columns. If space is a concern, take that into account (but it usually isn't). Therefore if you have more than 1 column of this sort, you will see a space savings over char(1) and tinyint, both of which will take up 1 byte per column.
Space isn't an issue, and that makes sense about the index. I noticed that enterprise manager doesn't let me select a "bit" field for an index. So that leaves which is easier from the view point of someone quering the data, and more importantly, which method is easier for the programmer doing the windows forms and the coding.
Because of this, I tend to store most fields, that really should be a bit into a tiny int field, allowing 255 various alterations to the scope of that. Of couse, you could just add an additional lookup table, and an additional field following the usual Normalization rules.
Imaging you are storing whehter a property has a basement, firstly you specify whehter it has, hasnt or unknown - 3 states 0,1,NULL. But then some hotshot project manager rolls in and wants to determine from that whether, its 'Basement, Slab, Crawlspace, Multilevel, etc' Now you are going to have to add an additional table and field for the lookup - whils if it was stored a tinyint field, you could simply add new values to the original lookup table. Job Done.
True, if your field is not a true/false type answer, then I wouldn't recommend bit; however, if a change is being requested to change to a multi-option answer, then that is going to require an application change anyway, plus a possible lookup table add. At that point, you have to revisit the database anyway...
The numeric and date fields need to allow Null if the value is unknown, but should the character fields allow Null to be consistent with the numeric and date fields, or should they use a special value to indicate Unknown or N/A? What is more correct from a database design view? Also, is it better to set up a table with the valid values of Y,N and make it relational to all the columns that use Y,N, or is it better to set up a user defined datatype that has a Y,N constraint?
I would use a primary/foreign key in my design, but that is because user defined data types are discouraged where I work. For character fields, I typically use null, but from a design point of view, I look at NULL as an absense of a value. So if you want a value of N/A, it wouldn't hurt. Although it would require some effort, as using NULL is the easier solution.
Portability is something you bring up quite a bit, in your articles and books and in this forum. Is there an article that could put me on the right track? Or is just a matter of reading the standards and sticking with them? Maybe you should write an article for SQLServerCentral!
I've used a variation of your "nested set" model to build a navigation tree for our company website (I do webdev as well as DBdev). It worked pretty well, but was rather complex. I also handled this using a loop, and although this was simpler it wasn't set based and didn't perform well for large datasets. Recently I've explored using XML data instead of relational data for this particular problem.
The contents posted on Amazon look interesting, though; looks like you've figured out some new tricks. I may need to pick it up (as I can get my company to pay for it anyway). Although XML does have it's place, I prefer relational data any day.
