Question

如何打开DSN文件

Answer 1

1、首先点击open,
/iknow-pic.cdn.bcebos.com/3b292df5e0fe992500dd938b3aa85edf8cb1711c"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/3b292df5e0fe992500dd938b3aa85edf8cb1711c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/3b292df5e0fe992500dd938b3aa85edf8cb1711c"/>
2、然后按照图示方法打开DSN文件，

/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d328db8edf990a304e241f5874"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/32fa828ba61ea8d328db8edf990a304e241f5874?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/32fa828ba61ea8d328db8edf990a304e241f5874"/>
3、由于没有工程文件，跳出建立工程文件对话框。点击OK，
/iknow-pic.cdn.bcebos.com/ac4bd11373f0820248bb6be445fbfbedab641b3b"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/ac4bd11373f0820248bb6be445fbfbedab641b3b?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/ac4bd11373f0820248bb6be445fbfbedab641b3b"/>
4、然后原理图文件会被打开。此时，打开的dsn文件会以完整路径显示，如图。
/iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539cbddf5183487e950342ab00d"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539cbddf5183487e950342ab00d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539cbddf5183487e950342ab00d"/>
5、同时发现，在DSN文件夹下，生成了一个同名的opj文件，
/iknow-pic.cdn.bcebos.com/21a4462309f79052f80ebde502f3d7ca7acbd5dc"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/21a4462309f79052f80ebde502f3d7ca7acbd5dc?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/21a4462309f79052f80ebde502f3d7ca7acbd5dc"/>
6、如果此次关闭后，下次再次打开该dsn文件则只会显示文件名（因为已经建立过了工程文件）
/iknow-pic.cdn.bcebos.com/4d086e061d950a7b46fcb41f04d162d9f3d3c924"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/4d086e061d950a7b46fcb41f04d162d9f3d3c924?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/4d086e061d950a7b46fcb41f04d162d9f3d3c924"/>
