小弟之前用BCB玩過EURESYS的picolo擷取卡驅動，最近又開始重新寫發現

驅動的程式碼都編譯過了，"multicam.def"檔案也加在Project裡面(如附檔)，

比照之前寫的驅動程式碼(影像正常顯示)是ㄧ樣的，重新寫的卻沒有影像出來，

我好像少了ㄧ道程序太久沒寫忘記了>"<，希望有接觸過的大大們，可否指點一下小弟><

卸卸!!

以上程式碼跟我之前寫的(正常Work)一樣...只是把它貼在新的視窗就掛囉><
我在想會不會是我加"multicam.def"檔案在Project裡面的方法不對，我是直接在Project右鍵Add....

編輯記錄

你的附件這樣看不出哪裡有問題
可能PO 出你的code 比較快喔///

請大大指點，Code以po上^^

印象中記得 使用 picolo 不需要設定  camfile
McSetParamStr(m_Channel,MC_CamFile,"IPX-1M-48L-Single.cam");
