I am reading data from a large excel file which has got formatted texts. I extract the data to DataTable object through oleDBConnection & GetOleDbSchemaTable . But the extracted data doesn't include any formatted information. My requirement is, I need to extract only non-Strikethrough texts.

I know that a very similar question has been asked here , but the answer didn't help me. I am using Entity Framework 6 with the Oracle.ManagerDataAccess.Client. If I define the connection string in app.config, then the connection works. If I specify the identical connection string in code, then I get the error The value's length for key 'data source' exceeds it's limit of '128'. which is correct. This is my connection string (with some names removed): "User Id=xxxxxxxxxxx;Password=xxxx;Data Source=( DESCRIPTION = ( ADDRESS_LIST = ( ADDRESS = (PROTOCOL = TCP)(HOST = VS-ORACLE.xxxxxxx.de)(PORT =

由 随声附和 提交于 2019-12-02 02:49:11
问题 I have a large ADO.Net dataset and two database schemas (Oracle) with different constraints. The dataset will work with either schema, but I want to be able to tell the dataset which schema to use (via connection string) at runtime. Is that even possible? 回答1: In the .Net 2.0 world, you can change your connection string on your table adapters at run-time. You just have to be sure the Connnection property is public, which can be set from the dataset designer. 回答2: Datasets don't know what

问题 I have a very strange situation happening and I'm hoping someone here knows why. I have TCP/IP enabled for all ports on the default port 1433.

Note2: The connection string doesn't matter since
