Cov ntsiab lus ntawm databases (DB) tau muab cia rau hauv cov rooj, tab sis cov ntaub ntawv feem ntau yog nthuav qhia rau tus neeg siv hauv ib daim ntawv yooj yim dua - cov ntaub ntawv thiab cov ntawv ceeb toom tau tsim. Ua kom pom tseeb, lawv suav nrog ntau yam duab: duab, duab, cim. Nws yooj yim dua los khaws cov ntaub ntawv duab hauv cov liaj teb tshwj xeeb. Microsoft Access DBMS txhawb ntau txoj kev xaiv rau kev thau cov duab rau hauv lub database.
Tsim nyog
- - Microsoft Access DBMS;
- - cov duab ua ntaub ntawv muaj duab.
Cov Lus Qhia
Kauj ruam 1
Ntxiv ib qho OLE khoom teb rau hauv lub rooj database. Nws nyob hauv daim teb no uas Microsoft Access tuaj yeem khaws cov duab. Qhib cov ntaub ntawv yuav tsum muaj thiab hauv "Cov Ntawv" tab xaiv lub caij uas koj xav tso daim duab. Hu rau tus tsim qauv rau lub rooj. Kev hloov kho nws cov qauv, ntxiv ib daim teb ntxiv nrog rau cov ntaub ntawv hom "OLE Object Field". Muab nws lub npe thiab txuag lub hauv paus kev hloov pauv ("Cov Ntaub Ntawv" - "Txuag").
Kauj ruam 2
Tso tus kwv OLE rau hauv tsim ntawm lub tshav pob, i.e. daim duab nws tus kheej. Ua li no, qhib lub rooj hauv cov saib hom. Koj yuav pom kab ntawv ntxiv. Tso tus cursor tso rau hauv lub xovtooj uas xav tau thiab nyem-los mus nqa cov ntawv qhia zaub mov. Xaiv hom lus txib hais kom ua.
Kauj ruam 3
Hauv lub thawv ntawv qhib uas qhib, qhib ib qho ntawm txoj kev xaiv thov ntxiv rau. Koj tuaj yeem ntxig rau daim duab kab ntawv uas twb muaj lawm lossis tsim nws ua ntej hauv cov ntawv xov xwm uas tsim nyog thiab tom qab ntawd txuas mus rau qhov chaw tam sim no. Hauv thawj kis, xaiv daim ntawv thov uas koj xav tau los tsim cov duab tshiab hauv "Khoom Ntaus" teb, piv txwv li, "Paintbrush Drawing". Nyem rau ntawm OK khawm, qhov khoos phis tawm yuav pib tib lub sijhawm. Qhov kev qhia ntawm tus kwv mus rau hauv lub chaw khaws ntaub ntawv yuav xaus tom qab koj kaw daim duab thov tom qab tsim daim duab.
Kauj ruam 4
Txhawm rau ntxig rau daim duab uas twb muaj lawm rau hauv daim teb lub rooj, xaiv qhov kev xaiv thib ob - qhib lub "Tsim los ntawm cov ntaub ntawv" hloov hauv lub thawv. Nyem rau ntawm lub pob "Tshawb …" thiab qhia cov kab thiab lub npe ntawm cov duab nraaj nrog daim duab. Nws yog qhov tsim nyog kom muaj daim duab hauv.bmp lossis.dib hom ntawm daim disk. Yog tias tsim nyog, qhib lub thawv "Txuas" hauv lub qhov rai - qhov no yuav tso cai rau DBMS los taug qab cov kev hloov pauv ntawm daim duab kab ntawv thiab rov thau cov duab hauv lub rooj.
Kauj ruam 5
Tshaj tawm ntawm kev rub tawm ntawm cov ntawv los ntawm nias lub khawm OK, tom qab ntawd khaws cia hauv database. Thaum koj qhib lub rooj hauv cov saib hom, OLE object teb yuav tso saib tsis yog daim duab nws tus kheej, tab sis cov lus sau "Bitmap". Cov duab nraaj yuav thauj tawm los ntawm lub rooj thaum tus neeg siv tsim thiab ua haujlwm nrog cov ntawv thiab cov ntawv ceeb toom.
