Tem como eu adicionar um item numa listview que nem numa listbox
Ou seja sempre que adiciono um item numa listbox o item vai para o topo já numa listview isto ocorre ao contrario.
Existe alguma maneira de inverter esta ordem de adicionar itens numa listview?

Descobri
basta fazer isso aqui
nota2 = (6 * (peso1 + peso2)) - (nota1 * peso1)
nota2 = nota2 / 67
De qualquer forma valeu pela ajuda
-
Testei aqui e me retorna uma mensagem com 1,9 sendo que o certo seria 5,6 para me dar a mediafinal acima de 6
Tem alguma coisa errada ali
-
não seria bem isso que eu queria
Tipo eu sei que eu substituir lá em nota 2 em vez de 5 eu colocar 5,6 eu vou ter media 6 correto
então o que eu quero é descobrir quanto eu preciso lá no valor inicial de nota2 para que eu tenha uma media 6 entendeu?

Tenho como obter a media ponderada de duas provas da seguinte forma
nota1 = 7
nota2 = 5
peso1 = 33
peso2 = 67
mediaPonderada = (nota1 * peso1 + nota2 * peso2) / (peso1 + peso2)
beleza
se a mediaponderada ficar abaixo de 6 o aluno tem que fazer uma prova de recuperacao porem preciso informar ao aluno qual o minimo que ele tem que tirar na nota2 para que ele possa ter uma media ponderada 6
Como fazer isso?

Ok
Valeu

Sim na matriz eu tenho ela declarada como string e o seu conteudo são nomes e atributos referentes a estes nomes
tem como eu jogar todo o conteudoda matriz para uma variavel e depois salvar? mas aí como eu depois iria carregar em ordem}
O que você sugeria?
-
sim mas tem que ser este tamanho mesmo to guardando na verdade uma matriz de 200*22*22 toda ela cheia e o valo total é 677Kb
E agora como salvo isso super-rapido
-
Ok
você sabe porque dá overflow nesta linha de codigo
n = FreeFile()
Open App.Path & "\teste.txt" For Random As #n Len = 677600
Put #n, , matriz
Close #n
e como posso resolver?
-
está então se eu n quizer precisão posso colocar um valor maior?
-
Ok
Mas tipo digamos que eu sei que nunca passara de 30 caracters mas as vezes eu posso ter menos tipo 17, 18 etc e eu não definir o tamanho dela mas fazer manualmente o calculo considerando como tamanho maximo 30 havera algum problema?
Ou tem que saber exatamente o tamanho de cada dimensão?

Quantos bytes ocupa uma matriz definida como string
Como eu posso descobrir?
dim matris(10,4,2) as string
se fosse definido como byte dim matriz(10,4,2) as byte eu saberia definir já que bastava eu multiplicar (11*5*2)*1byte que é o espaço de armazenamento
Mas e a string como eu posso descobrir já que posso ter varios caracteres de diversos tamanho dentro dela?
existe alguma funçao?
-
está o tamanho está errado....então como posso resolver isso?
me da um exemplo
-
Mas da erro de overflow...você sabe porque isso ocrre?
-
Tipo se meu reclength for de 405800 bytes dá um erro tem como resolver isso?
Pois o reclenght permite no maximo 32,767 bytes
Aguardo respostas

vlw kUROI

está mas como eu faço isso?
-
está mas como eu posso saber o tamanho do registro?

Deu um errro de Bad record lenght
-
COmo eu faria para salvar uma estrutura que tem arrays? Eu teria que criar um laço ou tem outro jeito de salvar?
exemplo
Type Estrutura Array1(3) As Integer array2 As Byte End Type Public teste(10) As Estrutura
Private Sub Form_Load() teste(1).Array1(1) = 2 teste(2).Array1(1) = 4 teste(3).Array1(1) = 6 End Sub
Private Sub Command1_Click() Open App.Path & "\teste.txt" For Output As #1 Print #1, teste Close #1 End Sub
só que da erro e eu naõ queria usar um laço
-
Ok já consegui
-
Achei uma maneira aí vai
Coloque um SStab no form
coloque o codigo no form
Private Sub Form_Load() 'função para converter a cor do sstab SetStyle SSTab1.hWnd, cSolidColor 'este ultimo parametro é que define a cor SetSolidColor SSTab1.hWnd, &H40C0& SSTabSubclass SSTab1.hWnd End Sub

Listview que nem listbox
em Visual Basic
Postado
Vou usar apenas uma coluna pois a ideia é usar a listview para dicionar uma narração de jogo de futebol parecidada com a que tem na globo.com onde a ultima frase adicionada sempre fica no topo da listview e o restante vai descendo entendes?
já tentei usar a propiedade sortOrder para lvwDescending mas porem ele ordena somente ate 9 posicoes apos isso ele não ordena pois acho que a decima posicao ele entenda como 1 ou sei la.
alguém tem uma solução?
Pensei em usar uma listbox que seria o ideal mas porem não tem como adiconar icones dentro de uma lisbox ae não me serve
